C-M-delete is not the most fortunate choice since it can induce a reboot on some systems (e.g. on the GNU/Linux console or on MS-DOS). On Windows, it invokes the task manager IIRC.

I'm not sure if you intended to preserve the key binding, let me just point out that ^? (which was in the original example) is (ASCII) DEL, i.e. usually [backspace], not [delete] on (modern?) text terminals. Štěpán ^ permalink raw reply [flat|nested] 10+ messages in thread

The docstring for the sample minor mode says "the control delete key", and my DEL key returns delete. If there's a more apropriate key binding that does not reproduce the bug, it's fine by me.

Note we're talking about the DEL _character_, not the key labeled Del(ete). It's the Backspace key that usually sends DEL in the terminal (also note that the example speaks about deleting all _preceding_ whitespace). I suspect "the control delete key" wording comes from times when the keyboards were somewhat different from those of today. But it's only an example, so all this perhaps doesn't matter. I just thought I'd mention the semantic shift introduced by the change, sorry. Štěpán ^ permalink raw reply [flat|nested] 10+ messages in thread
