I use synergy for sharing keyboard/mouse on my mac/pc.
I need to switch the alt(option) key mapping to meta, and I need some tool if this works.
What kind of tool is used for checking the key code that is send when I hit the key?
You can simply create a HTML to do so.
I'm struggling with exactly same case!
HTML checker by @wilson is working just fine with two little exceptions: it doesn't capture fn nor power (which actually what I want to make use of)
Found on the internet (using AutoHotKey)
(F13 in my case doesn't work, clipboard remains empty) http://www.autohotkey.com/docs/KeyList.htm
Maybe there is a way to read keycode and send it using these codes: http://msdn.microsoft.com/en-us/library/windows/desktop/dd375731(v=vs.85).aspx
(my case is even more complicated as I'm using polish layout and there is another layer of complexity with diacritic marks)
