In the mac terminal application there is a setting (preferences -> keyboard) that lets you set "use option as meta key". This is useful as a lot of unix boxes use bash as default shell and that has emacs keybindings M-f and M-b that let you skip words.

I am writing a terminal-based application, but I want the user to be able to edit certain text data in a separate editor. For example, if the user chooses to edit the list of current usernames, the list should open as a text file in the user's favorite editor (vim, gedit, etc.). This will probably be an environment variable such as $MY...
I'm trying to get my Emacs shell to mimic that of my standard terminal sessions. Basically I would like it to respect the same PATH as well as the command prompt. So far I have a few issues: PATH isn't found, below is the fix I'm using for that. I'm getting ascii color codes all over the place with another fix I tried. I have the f...
Hi all. I've been Googling for a while looking for a simple way to do this, and I can't find one. I have a custom terminal environment set up (zsh) with various aliases and functions to make things easier.

Using terminal sequences, I can colour text in a terminal emulator: $ echo -e '\e[37;41m--this is white on red--\e[0m' And this works.
