Help with making the ESC key "go back" in my fake menus

[Jason C.]

Hello all (and Nicholas),

Can someone please help me with an early issue I'm having. I pruned my project code down to around 100 lines that still capture the problem.

I put the exact problem I'm having in a comment near the top:

# The biggest thing I am having trouble with is getting these menu layers to go

# away ("pop off" in stack terms) when I hit the ESC key (for now I am just trying

# to get it to work from the first/"main menu" form). You can see I tried

# adding switchForm(None) (side question: should I be using setNextForm(None)

# for more proper transition/cleanup?). It seems that maybe the MultiLine itself

# is consuming the ESC key? I am using "xterm-256color" Mac Sonoma Terminal?

# Even when I continue hitting ESC, the form itself doesn't seem to go away (after

# I put in the add_handlers code in MainMenuForm)? I can tell the first ESC kind of

# "gets out" of the MultiLine widget (edit mode or active mode or whatever) in some way,

# because I have to hit arrow twice to get line selection going again (after the

# initial ESC press). Thanks in advance for any help! I would also really appreciate

# any feedback if you see me doing anything in a wonky/unintended way. Thanks again!!

# Note: I'm using Python 3.12 venv.
