not sending VK_?WIN and VK_APPS. possibly hotkeys being stolen.

VkKeyScan() doesn't get proper shift state unless we map shift
|
|
(etc?) to VK_SHIFT not VK_LSHIFT or VK_RSHIFT.

translate keys to keysyms
|
|
shift state is embedded in keysym
|
|
alt/ctrl/meta are stored separately, also caps/num/scroll lock
|
|
shift state also stored separately
|
|
|
|
Win32 to keysym:
|
|
VK code + shift -> keysym via table lookup
|
|
Win32 from keysym:
|
|
VK code and shift via table lookup
|
|
must synth shift key events to get correct character for key
|
|
|
|
don't allow leaving screen when any key is down
|
|
that includes shift keys
|
|
caps lock, etc must not be down but can be on

clipboard stuff:
|
|
PRIMARY -- the current selection, normally pastes with middle-mouse
|
|
CLIPBOARD -- set by cut/copy menu items, pasted via paste menu item
|
|
synergy must track and transfer both. however, only X clients need
|
|
the PRIMARY sent to them.
