Yes, this works for me. > but this does not have correct behavior: > > \bind "M-m h" "math-insert \\hat" > \bind "M-m S-H" "math-insert \\widehat“ No, this works for me too. \bind "M-m H" "math-insert \\hat" \bind "M-m S-H" "math-insert \\widehat“ And this works for me too. > And for Kornel, neither one of the above pairs of bindings has correct > behavior.

Yes, both combinations work and insert \hat resp. \widehat. To be more precise I have to explain how the modifiers are interpreted on a Mac - there are eight modifier keys on a Macbook-keyboard. From left to right: Shift - (left shift to reach the upper level (xev output: Shift_L, keycode 64) Function - to reach the special functions next to F1 .. F12 - not used (no xev output) Control - (left) control (xev output: Control_L, keycode 67) Option - (or Alternative) left option key (xev output: Mode_switch, keycode 66) Command - left command key (xev output: Meta_L, keycode 63) Space bar Command - right command key (xev output: Meta_R, keycode 71) Option - (or Alternative) right option key (xev output: Mode_switch, keycode 69) Shift - (right shift to reach the upper level (xev output: Shift_R, keycode 68) The left and right variants of the Shift, Option and Command modifiers are interpreted like-wise and there is no difference between them - at least Mac apps. Usually we have the Command-modifier bound to the C-modifier of bind file and the Control-modifier to the M-modifier of bind file. The Option-modifier should be the A-modifier and is not used intentionally because most key combinations with Option-modifier are mapped to special symbols like @ € µ º å and so on. The users expect them to work as in other applications to insert non-ascii letters. The mapping of the Command- and Control-modifiers can be made like non-Mac users are used to - this is a boolean preference option. LyX is shipped with Mac defaults. Obviously the literal letter keys are not case sensitive in bind file. I think this is because the output of keypress on „H“ is a lower case „h“ and the combination of „Shift“ + „H“ gives you upper case „H“ - there is no key named „h“ (at least on my keyboard :) Stephan
