About Hotkeys for painting & easing

Good morning.
I am a new student to 3D sclicer.

I am using 3D sclicer for masking,
I am looking for hotkeys to change the painting and erasing modes.

It is very difficult to change the mode by pressing the mouse every time.

Please help me out.

There are hotkeys already available for many functions during segmentation but you can add more custom shortcuts for any features by adding a few lines to your Slicer startup file. If you need any help with adding a shortcut to any specific feature then let us know.

You can automate not just simple steps, but you can also add shortcuts that perform a series of tasks that you need to do frequently.
