Alt and ESC reversed

[balanga]

I have just made a fresh installation of 14.0-R and installed xorg, tmux, emacs on an old ThinkPad X61.

Using emacs, under tmux under xterm, I need to press ESC to invoke Alt, how do I get Alt to work normally?

 

[balanga]

The problem occurs under x11/xterm. I have to press ESC when I want Alt.

When pressing Alt (left) x11/xev shows 64 Alt_L, and 9 Escape when pressing Esc.

This is under 13.2-R-p2 on a ThinkPad X61 which has a 7 row keyboard. Not sure if that is a contributing factor.

How do I fix this? x11/xmodmap? If so can someone give an example of how to do this?

Add the following line to ~/.Xresources

XTerm*metaSendsEscape: true

xrdb -merge ~/.Xresources

After watching

I couldn't see any changes after running xmodmap().

How do I display an XTerm keymap before and after running xmodmap?

xrdb -merge ~/.Xresources

or
Hold down Ctrl and right left click on Xterm and check 'Meta sends Escape'.

xmodmap -pk

I see VT Fonts. How do I '"check 'Meta sends Escape'"?

xmodmap -pk

Am I right in thinking that the output should change after 'Meta sends Escape' has worked?

I made the mistake because I use the mouse with my left hand.
Drag the 'Left' button while holding down ctrl and release with "Meta Send Escape".

No change.

Not sure what I did wrong earlier but this does work now, although I still have numerous keys not working properly under XTerm...

Having said that, it looks like they do work in other applications under XTerm, but emacs has most problems... C-h (help) acts as backspace, for example. There are several other keys in addition. This is confusing because the same keys work fine under LXTerminal

Does seem like an emacs rather than XTerm problem?

you can create custom xkb settings to swap any key even on wayland

heres my macbook air dotfiles i use to swap alt super and ctrl
that should point you in the right direction

Unfortunately I can't get my head around what is going on....

The problems manifest themselves under emacs, eg C-h invokes backspace among other irregularities, but only under XTerm. It works normally under LXTerminal. I'm not aware of any differences between XTerm and LXTerminal in other programs.

looks like tmux causing the issue

tmux - stealing Alt key from Midnight Commander, emacs

just starting to use tmux. I really like it so far -- a solid replacement for screen. The one single problem I have is that tmux steals the Alt (meta) key presses from a Midnight Commander running

That may have been the case, but I've eliminated tmux from the equation and have found that I can use C-h in emacs under LXTermnal but not under XTerm.

Not sure how to trap what keycode gets sent when pressing C-h.

Xev seems to treat the keys separately.

i found a couple of links that might be useful

Keybinds on xterm and emacs-nox

I've looked on google, stack exchange, GNU emacs manual, xterm manual, etc. and still haven't found an answer that satisfies my problem(s). Problem: Using Systems: Ubuntu 16.04, xterm, emacs-nox I

emacs.stackexchange.com

Why does emacs in an xterm on a Mac interpret c-h as backward-delete-char?

C-h is correctly interpreted has 'help' in Carbon Emacs.app and using /usr/bin/emacs in Terminal.app. I'm sure I'm missing something simple here. Emacs describe-bindings shows c-h is rightly mappe...

if you google the link that doesnt work thr first hit is the arch linux forum

[SOLVED]tmux key-binding doesn't work for one key only / Applications & Desktop Environments / Arch Linux Forums
