Blender 2.8 - What is 'Tweak' in Preferences > Keymap I've used Blender 2.7 for years, but I'm really trying to make an effort to figure out 2.8.

I was trying to randomize my vertices in edit mode; so I searched Preferences > Keymap for the shortcut to do this. Sure enough, it appeared as the following:



But what is tweak?? I'm guessing it's some hidden menu or something?? I've Googled for awhile, and cannot find anything about this.

TIA
Tweak is for when a mouse button needs to be pressed and held, followed by dragging the mouse. You can find this information in the docs of Blender 2.8.

A good example for this is SHIFT + Right Click. As long as you keep the right mouse button pressed, you can drag the 3D cursor around.

I couldn't find a particular purpose of having transform.vertex_random set to tweak, it doesn't seem to react to mouse drags. Perhaps that's a misconfiguration.
