以下はIDLEのHelpからの抜粋です.
Backspace deletes char to the left; DEL deletes char to the right. Control-backspace deletes word left, Control-DEL deletes word right. Arrow keys and Page Up/Down move around.
Control-left/right Arrow moves by words in a strange but useful way. Home/End go to begin/end of line.
Control-Home/End go to begin/end of file.
Some useful Emacs bindings are inherited from Tcl/Tk:
Standard Windows bindings may work on that platform. Keybindings are selected in the Settings Dialog, look there.
Control-c interrupts executing command.
Control-d sends end-of-file; closes window if typed at >>> prompt (this is Control-z on Windows).
Alt-p retrieves previous command matching what you have typed.
Alt-n retrieves next. (These are Control-p, Control-n on the Mac) Return while cursor is on a previous command retrieves that command. Expand word is also useful to reduce typing.
