I think, it is better to have a short cut list to place it near your keyboard. Maybe, sorted by your own preferences.

Many short cuts rely on where your mouses pointer is. For instance, if the mouse pointer is in the 3D view, the short cut u opens the uv options, if it is in the uv view, it calls something different and so on.
Basic orders of short cuts are needed to perform certain actions.

For instance, key_g while the mouse is in the 3D view let you move the selected with the mouse, clicking z or x or y let the move restrict to the directions z or x or y, clicking the left mouse button confirms the change.

Middle mouse button is for moving the camera around a certain point in the 3D view, you can select the certain point and move to to circle the camera around a different place in the view and so on...

It is more about the huge amount of options that you have to discover whether by short or by voice control.
