I tried switch to previous preset but it only switches between brushes not between Color picker and Brush.
In Clip Studio Paint when painting if you held the hot key sat E for eraser the tool would switch to the eraser then when you let go of the hot key it would go back to the Previous tool (say brush) is there a function in Krita that works this way? Thank you.

Hello!

Krita works a bit differently. You can toggle the "Eraser" mode for your current brush preset by pressing E. So you'll be erasing with your current brush, rather than a separate Eraser tool. If you have a specific preset for an eraser, you'll have to switch to it the same way as any other brush preset.

You can however set up some more convenient shortcuts via the Ten Presets script, found in in the top menu under Tools -> Scripts.

Hi,

1. color picker: I keep pressed the "CTRL" key and click, or hit the "P" key (it switches to the Color Selector Tool, I hit the "B" key to switch back to the Brush Tool)
2. eraser: I toggle the "E" key to switch between the current brush tool and the eraser

Does it help in your case?

(I'm on Linux and using the latest 4.2.0-pre-alpha, btw).

Yes both answers are helpful Thank you mvowada and kappa.
