Linux users should remember that what your physical DEL key *actually does* depends on a lot of things, and whether it will do what you *want* depends on whether your program is expecting one of those things.
It doesn't always send 0x7F (ASCII DEL). A lot of times, it sends a VT100 DEL sequence (ESC mumble 3) and sometimes it even sends 0x08 (ASCII BS).
Even in native X window system apps, like browsers, though, your DEL key *still* might have been remapped -- and worse, it's at least possible that it's been remapped to something that your browser itself listens for, but your app does not. |
