Redirected from Howto use short-cut keys in xterm and other terminals

Xterm and other terminals through terminal control characters based on the type of terminal emulation. Commons terminal type are VT100...


Note : Most of these keystrokes come from the readline library, and have nothing to do with the terminal type or terminal emulator used (except that some terminals emulators don't play well with control/meta keys). When using bash (which uses readline), a list of shortcuts it offers is obtained by entering "bind -P" at the command prompt.
