[Wine] Host key equivalent for wine+desktop emulation+mouse capture

[diegogmx]

hi, i installed SC2 yesterday however ive got an ati card and i need to emulate a desktop and allow dx apps to hold the mouse in its window, however, i think it would be useful to press a couple of keys and release the mouse for use in other applications just as you do with a vm
i just wanted to know if there is a way to do it
thanks in advance
