I've added a new boolean variable called lyxrc.mac_dontswap_ctrl_meta and 
successfully connected it to a checkbox in the Keyboard Preferences. The 
default value is false (meaning the current standard behavior - this follows 
the nomenclature of Qt::MacDontSwapCtrlAndMeta). Then I added the line


in  GuiApplication::execBatchCommands()

right after

#ifdef Q_WS_MACX

Everything is working great. I can set the preference and it gets applied when 
the application is re-launched (maybe one could apply it immediately, but I 
wasn't sure how I can then make sure that the menu shortcuts are updated to 
display the correct modifier keys). If anyone sees something wrong with this 
approach, please let me know.

To avoid problems with earlier Qt versions, I will (but haven't yet) enclose 
all my code in: 

#if QT_VERSION > 0x040600

and if it isn't already there, I'll also put in 
#ifdef Q_WS_MACX

All my testing was done with the official lyx-1.6.1 source release, so my next 
hurdle will be to get an SVN version to build. I haven't tried that for several 
years, so I may have some  questions tomorrow... if all else fails, I could 
perhaps just send the diffs to the official release.
