0001386: [Bug][?] Don't see F1-F10 keys in Linux, F11, F12 wrong.

Yes, I see it too. I suspect this is a side-effect of how we're translating key strings in the VM. If you compile with DEBUG_EVENTS defined you'll see the translation. What we're doing is calling XLookupString(). Then if it doesn't come up with a character code, we're trying to translate the symbolic keyname. Now in this case, XLookupString() results in no bytes. Output below from xev (1): KeyPress event, serial 27, synthetic NO, window 0x3400001, root 0x7c, subw 0x0, time 2167463, (280,699), root:(286,719), state 0x0, keycode 76 (keysym 0xffc7, F10), same_screen YES, XLookupString gives 0 bytes: "" KeyPress event, serial 27, synthetic NO, window 0x3400001, root 0x7c, subw 0x0, time 2170356, (280,699), root:(286,719), state 0x0, keycode 95 (keysym 0xffc8, F11), same_screen YES, XLookupString gives 0 bytes: "" But... there's special logic in there for Sun keyboards. And the Sun keyboards use the same keysyms as F11 and F12... #define XK_F11 0xFFC8 #define XK_L1 0xFFC8 #define XK_F12 0xFFC9 #define XK_L2 0xFFC9 #define XK_F13 0xFFCA #define XK_L3 0xFFCA And the special logic says (in translateCode()): # define ALT (8<<8) switch (symbolic) { case XK_L1: return ALT+'.'; /* stop / case XK_L2: return ALT+'j'; / again / So in the case of (for instance) F11, translateCode() returns 0x0800+0x2e, or 0x82e. Then the return value of translateCode() is used as a lookup in a table with 256 entries... if (nConv == 0 && (charCode= translateCode(symbolic)) < 0) return -1; / unknown key */ if ((charCode == 127) && mapDelBs) charCode= 8; if (charCode >= 128) charCode= X_to_Squeak[charCode]; return charCode; So we get whatever is 0x72e bytes past the end of the table. Which is apparently 0. This is probably a bug."

However in my case when I hit F11 or F12 I get a debugger that claims there has been a 'User Interrupt' and the resulting debugger gives me errors.
