Keyboard input

[ModProg]

Is your feature request related to a problem? Please describe.
It's frustrating to write a whole layout in zmk studio, as you can neither use your keyboard to input keys nor do there seem to be keybindings to navigate the app.

Describe the solution you'd like

1. A way to input a key by pressing it i.e. press the A key to create a key typing A.
2. A way to navigate the keyboard layout quickly and define more keys like that. I imagined a workflow like so:

• Arrow key to get to key
• Enter to get into edit mode
• Now the Behavior input should be focused so you can select e.g. "Key Press" here and continue navigating with TAB. Afterward, get back to the focused key with ESC.
