Windows Keyboard Shortcuts – Difference Between Alt+Tab and Ctrl+Alt+Tab

I would like switch Alt and Ctrl because I'm currently a Mac user on Window (with a PC keyboard). All hotkeys on Mac: Cmd+n, Cmd+w ... -> PC: Ctrl+n, Ctrl+w and Cmd got same place as Alt key.

I found a non perfect solution:

Map all letters like that :

LAlt & a::Send {LCtrl Down}{a}{LCtrl Up}
...
LAlt & z::Send {LCtrl Down}{z}{LCtrl Up}
LCtrl & a::Send {LAlt Down}{a}{LAlt Up}
...
LCtrl & z::Send {LAlt Down}{z}{LAlt Up}

And you will keep Alt+Tab and AltGr functional

This is my full implementation (non complete): http://www.pastie.org/1660132

Alt+Space, C is a sequence that uses Alt+Space to open the window controls menu¹, and then C to select the Close option.

Activating the Close option in this way is normally the equivalent to using Alt+F4, and so Windows will issue the process a WM_CLOSE signal, telling it to terminate.

As with Alt+F4, a program can catch and/or ignore this command (often for very good reasons - think of Word's "do you want to save before you quit?" dialog box, for example).

^{1. I've just made this name up for it, it probably has a real one somewhere.}

Ctrl+W is a shortcut only provided by the program, and the program can choose to handle the shortcut in whatever way it sees fit.

This involves no action by the operating system.
