Description Alexandre Rostovtsev 2011-11-19 19:03:59 UTC

As the summary says: Shift+Backspace and Shift+Delete fail to work both in xkeyboard-config-2.4.1 and in xkeyboard-config current git head (a0e5adf1).

Here's the xev output for pressing Backspace with xkeyboard-config current git head:

And here's the xev output for Shift+Backspace:

Comment 3 Sergey V. Udaltsov 2011-11-20 11:58:26 UTC

Thanks, I see the issue with BKSP. What do you see in xev when you press Delete and Shift+Delete?

Also, if you disable the option terminate:ctrl_alt_bksp - would shift+backspace work again?

Comment 4 Sergey V. Udaltsov 2011-11-20 12:04:18 UTC

I hope I fixed bksp in git. please check

Yes, Shift+Backspace works with git-a0e5adf1 if terminate:ctrl_alt_bksp is disabled.

(In reply to comment #4)

Yes, thank you! Shift+Backspace is fixed with git-81fc86a9 (works even if terminate:ctrl_alt_bksp is enabled).

With git-81fc86a9, when pressing Delete:

KeyPress event, serial 32, synthetic NO, window 0x2600001,
    root 0xae, subw 0x0, time 305101635, (120,20), root:(174,457),

When pressing Shift+Delete:

-----------

I now suspect that the Shift+Delete problem might be a toolkit issue, not a bug in xkeyboard-config. This is because I observe the same behavior with xkeyboard-config-2.3 (and the same xev output); and because while gtk+ and qt-based programs do not appear to recognize Shift+Delete, in xedit it has the same effect as the normal Delete key.

In other words, feel free to close this as fixed :)

Yes, DELE looks quite ok in your out.xkb. Closing the bug.
