You can right click canvas open transform tool menu when using Transform Tool, then toggle mode.
I sometimes modify Position value to make sure movement is accurate, and I’m sure someone will need to modify the Filter to keep pixel perfect. As for other options, I never used them.
These functions can be easily accomplished using python scripts.
example:
from krita import *
Krita.instance().action('Transform tool: liquify').trigger()
If you don’t know anything about python script, try this plugin.Shortcut Composer.
It offers a convenient pie menu for Transform mode.
I agree that we need shortcuts instead of python script. Understanding how python scripts work is not easy.
