[Wylug-help] X Keyboard Oddness

[Simon Wood]

This string of characters is probably because the keyboard is faking an extra key, without actually having a different scan code.

Under DOS (and probably Windoze) you can hold the Alt key down and then type the (decimal) ASCII code for a character. This character will appear once the Alt key is released.

I can't think of a way of implementing this on X. You may need to write a little application to capture the 'Alt+num+num+num-alt' sequence and insert the '@' back into the keyboard queue.

For examples on who to insert back into the queue you could look at the various 'On Screen Keyboard' Code.


Good Luck,
Simon.

Yes there is.

'Fraid not. Xev shows that it produces a whole stream of keypresses, which
equate to keying zero, six and four on the numeric keypad whilst holding
down Left-Alt. On the "other" OS, this enters the @ symbol when this
happens because the ASCII code for @ is 64.

Can the X keyboard gubbins be persueded to act in this way?
