What is this tool? I cannot seem to figure it out.

[John Springer]

Sorry if this is a stupid question, but I cannot for the life of me figure out what the bottom tool in my tool panel is.  It seems to be a masking tool but I can't find it in the manual and can't seem to use it properly.  (Affinity Publisher 2)

You mean, the Stroke and Fill color selectors?

Yes!  That's it.  One line of text in the help file: "Stroke and fill color selectors are available below the tools, along with an arrow that swaps their colors."  

No picture.  No info about using.  Guess I'll figure it out, but it did confuse me because I could see changes but couldn't figure out what happened.   I even searched for stroke and never found it.  But now I know.  Thank you.

You're welcome.

I agree that more could be useful, but that same Tool appears elsewhere (Color panel, Swatches panel, maybe others) so perhaps they figured users would recognize it.
