OK I’m testing on Kubuntu Xenial which has:
libx11-dev:amd64 (2:1.6.3-1ubuntu2) libxdo3:amd64 (1:3.20150503.1-2)
But a few things I’m not clear about:
XKeysymToKeycode(dpy,XK_U) seems to indicate that U is a necessary part of the input sequence. Yet the readme says only:
- Press Ctrl
- Press Shift
- Type the hexadecimal code, e.g. 3b4 for Greek delta δ
- Release Ctrl and Shift
I guess the README needs to be updated (and I’ll send in a pull request once the following problem is solved).
Anyhow, it is not clear whether the
U should be continuously pressed as well or only
Shift. From the GNOME official help and this SuperUser post it only seems as if Ctrl and Shift should be held down. I am assuming the same has been implemented by this applet. So that is what I am trying now,
But I am trying both GTK and Qt apps on my platform: I press
Ctrl Shift U, release
U while holding down
Ctrl Shift and I observe that my current application loses focus i.e. the text cursor disappears. I presume this is the “grab”. Then I input the
3b4 suggested in the README followed by space, but nothing happens except that my application gets back the focus i.e. the text cursor reappears.
I tried prefixing it by
0 but that doesn’t help either. I tried putting it in my autostart and rebooting but no fruit there too. I tried loading from a terminal to see if there are any error messages printed but nothing there either.
I tried on both GTK (Firefox) and Qt (KWrite) applications.
