Using the IR Command Line.

The keyboard package used by the IR user interface is GNU readline. This package allows history recall and command line editing. Moving between and within lines uses the arrow keys or a sequence of keystrokes as given below. A C-char == control-char, that is hold down the control key and type the character. A M-char == meta-char == Esc char, that is type the Escape key followed by the character key.

Here are the most useful key sequences.

• C-d delete under cursor
• C-k delete to end of line
• C-w erase word
• C- undo
• arrows move cursor right or left, move up or down history list.
• C-a move to beginning of line
• C-e move to end of line
• C-l clear screen
• C-f forward character
• C-b backward character
• C-n forward line
• C-p backward line
• M-f forward word
• M-b backward word
• TAB complete current command, filename or word
• TAB-TAB list all possible completions
• M-? list all possible completions
• <return> execute current line

Most prompts and commands have completion setup to reflect the possible inputs.
