I'm confused (Alt key and purpose)

Affinity Photo

Okay i draw with the brush tool, hold left alt and suddenly I'm able to resize my brush? few moments later I hold alt again and now it's a color picker? Is there a way to control this random behaviour?

To me alt activates the color picker but ctrl-alt let me change brush width (click-move left-right) and brush hardness (click-move up/down).

See:

• Keyboard shortcuts for Affinity apps
• In the online help - the related shortcuts sections bottom down

not for me, it change spacing and shape but not the brush size

And I'm aware of the shortcut PDF thing and so on, but the docs weren't really helpful

You can check what is setup in the related Affinity preferences under the keyboard shortcut settings and if something isn't setup the right way for you manipulate (change/reassign) the settings.

maybe you did a single click before click-drag? With a single click when holding ctrl-alt you toggle between size/hardness > shape/spacing > rotation.

Well that was the issue. I didn't knew about this because obviously, I don't draw with my mouse and my pen doesn't have a right and left mouse button and still, by pressing my pen on my tablet and pushing the alt button i could change the brushsize for ...10minutes? then the function disappeared and now it's a colorpicker. The very reason I'm actually confused.
