Feature request: implement a metashell command prefix or escape menu

[wvu]

This bit me again:

(gdb) help find
[-] No such command

There's no workaround when you're already in the program.

Edit: it was more convenient using gdb within the session than uploading gdbserver and matching the target with a cross-compiled gdb. I guess that much is on me.
