Hi I'm about to test this. I'm following this link
Step 1.
win+R→regedit
→HKEY_CURRENT_USER/Control Panel/Input Method/Hot Keys
00000010
is for enable or disable the IME
00000011
is for toggle between full and half width characters
00000012
is for switch symbol mode
Step 2:
Go whichever hot key you want to modify, right click on the item and select modify, here are the rules:
Key Modifiers(ref):
00 C0 00 00
, no Ctrl or Shift or Alt (Set this value if you don't need the hot key)
01 C0 00 00
, leftAlt
02 C0 00 00
, Shift
04 C0 00 00
, Ctrl
06 C0 00 00
, Ctrl+Shift
Or combination of the above to make your own.
Virtual Key code:
the actual key combination, ascii code
20 00 00 00
, for Space
21 00 00 00
, for PgUp
00 00 00 00
, for no key
ff 00 00 00
, for NONE (Set this value if you don't need the hot key)
Target IME:
leave it as it is, or change it to 00 00 00 00
, for all languages( I suppose).
