[feature]: Add keyboard shortcuts in edgeless mode.

[Ulysses Zhan]

1~3 main use cases of the proposed feature

I uses drawing tablet to draw and write things on my computer. Currently I use StylusLabs Write because it supports pen pressure and has many keyboard shortcuts. I want similar experience in whiteboard mode of AFFiNE.

Ideas for solution

• Hold Shift for eraser;
• Hold Ctrl for selection (better if it is lasso selection);
• Hold Spacebar for panning (already implemented);
• Use number keys (1, 2, etc.) to switch to different colors;
• Use letters (Q, W, etc.) to switch to different stroke types (highlighter, pencil, etc.).

what types of users can benefit from using your proposed feature
