software keyboard help needs to be more accessible

Now that I have a Gemini pda I use blink less often. When I do it’s a damned fine pleasure. However I struggle to find the software keyboard info especially for escape keys such as grappling with tmux and vim etc. perhaps a simple ‘> help’ at the prompt could pop up more info on keyboard layout?

Typically I am ssh to restart something and I lose a lot of time getting the keyboard sorted out.

No source files, tests, or entry points are named. Start by locating the software-keyboard information and the prompt help handling, then verify that the resulting guidance explains Escape and related keyboard use for tmux and Vim during an SSH session.
