Sequential Key Shortcuts

[BurnyBoi]

Requesting a way to make Key Shortcuts that require typing multiple keys sequentially. For example what I do on ranger and lf; I press g, followed by another key in order to run commands that navigate to different locations. A menu appears that show me all the shortcuts mapped under that key:

Other examples of non-navigation commands I have mapped under the d key:

I've tried making a script that pops up a dialog with buttons to see if I could press the buttons with hotkeys, as well as tried a script that uses read, but the only way it might work would be having a separate terminal window script. It'd be cleaner having sequential key shortcuts built in.

This is the dialog I tried. I was hoping I'd be able to press the m and v keys to press the buttons, but I either have to use the mouse or tab to them. If this were possible I'd be able to string together dialog boxes and buttons to achieve what I'm looking for.
