The Tab key hides/unhides the Studio panels and the toolbars. The ‘View > Studio > Hide Studio’ toggle (Ctrl+Shift+H on Windows) hides/unhides only the Studio panels.

When @Wosven wrote “we use a no breaking small space between number, not a quote”, she meant “we French speakers”.

From a typographer's point of view one of the worst personal insults in text processing software functionality was the introduction of "fake" bold and italic text formatting. And there's a simple reason to avoid doing this: it looks terrible. That is why specifically designed bold and italics font family members have always been the way to go.
InDesign, top of the crop in layout software, can't use bold formatting or italics either if the corresponding type family members aren't present. It is possible to skew text and/or scale it vertically and horizontally, but the end result generally looks horrendous, and is unusable for anyone looking for quality type.
Layout software such as PagePlus never aimed to please professional type setters, and oriented itself towards Word users wishing to gain more layout control, and who were familiar with instant fake bold and italics.
Like it or not, no self-respecting layout app ought to have a fake bold and italics facility to wrangle regular type members into ugly distorted versions. At least, that's the answer which you would get from a typographer and/or from many a professional layout designer.
Publisher aims at becoming a high-level layout app, aimed at creating professional looking print work. Therefore, there's no place for typographic aberrations like generated bold and italics, or terms such as "line spacing".
Disclaimer: this is not necessarily my own opinion. While I understand the typographical purist's view that I presented here, I think generated bold and italics can be useful under circumstances, even if one has to forego type quality.

APub only use "real" font, as in bold, italic, bold italic, etc. and it's how it should be.
You can create a faux italic with shear and faux bold with a stroke, but best practice is to avoid this and only use fonts with at least B, I and BI options.
Thin strokes can't be printed and some pro software like Pitstop will convert them to acceptable stroke width… messing the result. Shearing font will do a poor job of simulating an italic when the intended italic one would have been design with love and professionalism by the typographer.
One of the fisrt rule you learn in pro work is to respect fonts and font designer: avoid shearing, strokes to simulate bold, NEVER modify horizontal or vertical scale since if you don't know anything about how doing this discreetly it'll shout "amateur" to everyone (and creating such variant is really a work of adjusting design, width, optical perception…).
 
Sorry if I said this in a blunt way, I hope I would have done it better and with more diplomacy in my own language

Audrey Hepburn: Moon River (Vector) Portrait
(Affinity Designer/Photo)
https://b-bertuleit.de/audrey-hepburn-portrait/

I have just copied (a page) from inDesign (select all and copy), opened a new Affinity Publisher Beta document and pasted it. It worked flawlessly. All text is editable all vector work done in inDesign comes in as expected. Not sure how it would work with a multi-page document with linked text boxes but this is actually pretty amazing. This is just fantastic!

Right click the text and select Expand Field
Or use the Text menu to do the same

No need for the screenshot; that's enough of a pointer. Thanks, Wosven!

The same icon for layer adjustments appear at the bottom of the layers panel depending of the selection.  I'll add screenshot when at home.

It wold be great if Publisher added Right Tab to the white space characters.
I have a few more white space characters at the back of my mind that I would like to see added to Publisher but don't want to obfuscate waters at the moment.
I use the right tab very often in church documents when some responses need to be right aligned and then bolded.
Right tab is especially useful as a sentinel character for Grep Character Styles when defining Paragraph Styles (e.g. Indesign) which I'm hoping will be implemented in Publisher too.
 
Think also of Prices, ISBN numbers, etc. that you might want to apply automatically different characters styles to.

I can't see the point of doing bad review or videos for a bêta when it should point to the finished features we are to test and we suppose the other features missing or incomplete are a work in progress they didn't added.
Some basic roadmap could have been helpfull for people to focus on some features and wait patiently for other to be finished instead of complaining it's a total failure. I can see good potential in this bêta, and once some major features are finished it'll be able to handle part of some workflow.
But for complexe and technical work we'll have to wait for a more mature application, and that's normal. We can't expect a bêta or a v.01 to be a full replacement for apps that take years to develop.

Thanks! How strange we can't find our words when needed, I'll edit my post.

The standard English term is spine (definition 2 on the linked page).

I think you've got the wrong approach, you need to find specific training/lessons with someone able to explain to you how to do it and able to guide you and to answer your questions.
The most usefull book I read long ago were about Illustrator/Photoshop and QXP, and I read them away from any computer to really take time to understand and memorise things. It was the same as Serif documentation: each menu, option being explain.
Later, if I searched a fonction/option that I know existed, I only had to look at the index to find where it was in the menus.
When switching to a new app, the important part is to know the new name of features we usually use, and to check for new one, but basically it's the same in disorder (menus are differents, names too, etc.)
 
What do you need to do a (simple) book?
Simple Master pages to put your page numbers, title and author infos,  and (?) some decorative objects Perhaps another one for the begining of each chapters Understand how to apply master pages to your pages How to create sections How to create a main text frame on a page How to have your text flow and add automatically pages and text frame (autoflow) Those are covered in Affinity Publisher Help.
Once you'll be at ease with this, you'll try learning more complexe things as modifying, creating new Text Styles, etc.
You'll be able to add the first and last pages.
 
Since for now APublisher only accept pages of the same size in a document, you'll have to work on a cover on a different document, not made with 3 pages, but only one (which width = backcover width + spine width* + cover width)
* Depending of the final number of pages in your book, your printer should tell you the expected with for the spine.
 
Next stage you learn to add pages with pictures, pages with text and pictures and legend, etc.
Stay calm and procede with methodology, stress don't help. If you were able to do it in other apps, you'll do it with Apub
And the forum is here to help you with specific questions when you bug on a problem like everyone of us.

I think Ash did a great job! Without his tutorials I would have struggled to know where to begin.

Thoses ones below.

 
Transform tools are active now too, but I didn't test them really. They're used with the node tool.

I think you had a problem when you inserted your page numbers, try doing it again with menu Text > Insert > Page number
This will add a variable (can we have more and personalised ones?) that will change automagically on each page.

For now we can use some tricks since Master pages behave like Symbols in Designer.
You need to:
open the Layers panel, unlock the "master_page_name" corresponding to your current page (there's one for each page you applied your master page to), select the frames you want to modify and open the Symbols panel [detach] or un[Sync] before modifying the frames. It's not easy and natural, and I'll need to do it more that twice to be at ease doing it…
I hope they'll improve it

Be carfull to always work with showing Special Charaters, and using the shortcut ctrl+shift+w when you want to look at the final result.
This way, you'll be able to easily check that you text frames end with this character that means "end of the text" (=no overflow):

Like other apps APub will need to display a red mark that stay visible/big when zooming out to give us an easy way to  spot this usual problem.

Here you go:

I wonder if Paulus came here to check any of his problems before he posted that? We are so far behind answering queries at the moment he may well have. If anyone knows the answer to any query you read, feel free to nudge the new users in the right direction please. Hopefully by next week we will be back on top of the initial rush. 
Still 1.2K views is not to be sneezed at...  I may go and make a trash talk video myself
