Most important Operators / Key shortcuts

This will be a thread about making a collection with operators that deserve a better shortcut.

These so called “operators” must be an important part of your Blender use (and your own personal workstyle) and you must also consider that perhaps other people might be interested to adopt.

Here is mine.

Center View To Mouse (view3d.view_center_pick) = Alt Middle Mouse
(Alt-F works only in Object Mode and breaks on Mesh Editing)

View Selected (view3d.view_selected) = Ctrl Alt Middle Mouse
(I want to avoid lifting my hand from mouse and the left hand from resting position).
