20.10 Execute mode

The Listener is actually a special type of editor window, which is run in a mode known as execute mode . This means that, as well as the normal keyboard commands available to the editor, a number of additional commands are available which are especially useful when working interactively.

20.10.1 History commands

These commands are useful in the common situation where you need to repeat a previously entered command, or enter a variant of it.

History First

Editor Command

Emacs Key Sequence: Ctrl+C <

Replaces the current command by the first command.

History Kill Current

Editor Command

Emacs Key Sequence: Ctrl+C Ctrl+K

Kills the current command when in a listener.

History Last

Editor Command

Emacs Key Sequence: Ctrl+C >

Replaces the current command by the last command.

History Next

Editor Command

Emacs Key Sequence: Esc N or Ctrl+C Ctrl+N

Displays the next event on the history list. That is, it replaces the current command by the next one. This is not available if you are at the end of the history list.

History Previous

Editor Command

Emacs Key Sequence: Esc P or Ctrl+C Ctrl+P

Displays the previous event on the history list: that is, it replaces the current command by the previous one.

History Search

Editor Command

Emacs Key Sequence: Esc R or Ctrl+C Ctrl+R

Searches for a previous command containing a given string, which it prompts for, and replaces the current command with it.

History Search From Input

Editor Command

Emacs Key Sequence: None

Searches the history list using current input. That is, it searches for a previous command containing the string entered so far, and replaces the current command with it.

Repeated uses step back to previous matches.

History Select

Editor Command

Emacs Key Sequence: Ctrl+C Ctrl+F

Presents a list of items in the command history, and replaces the current command with the selection.

History Yank

Editor Command

Emacs Key Sequence: Ctrl+C Ctrl+Y

Inserts the previous command into the current one, when in a listener.

20.10.2 Debugger commands

These commands are useful when in the debugger in the Listener:

Gets a backtrace when in the debugger.

Debugger Abort
