Keyboard shortcut

[zysimplelife]

Is your feature request related to a problem? Please describe.
This is very nice setup and I found it is useful project. I understand it is in the start point of missing some fundamental features.
One of them is the keyboard shortcut for some quite often used editor features like

• Search files (not content). In VS code, there is ctrl + p in windows to open a command table to search file
• Jump back and forward. Using mouse is kind of inconvenient.
• Create a new note shortcut.

Describe the solution you'd like
Add default mapping as short term solution

Thanks again for the great work.
