| Subject: | XK_Alt_L should fall back to XK_Meta_L |
Hello,
Xvfb lacks XK_Alt_L keycode, so pressing ALT-something (e.g.
SendKeys($win, '%(h)a') for Help->About) simply does not work --
XKeysymToKeycode(display, XK_Meta_L) returns 0.
(Xvfb is a virtual X server that comes with XFree86 and XOrg; it can run
on machines with no display hardware and no physical input devices, thus
being a good choice for automated GUI testing.)
The following patch implements fallback to XK_Meta_L:

End of patch
It simply wraps XKeysymToKeycode() function into a macro.
(This syntax is GCC extension; it works fine for me now, though.)
