Recently, I start to using windows for my personal project. One thing I hate about is the keyboard mappings. I want to basically do the following mappings 1 Caps lock key -> Left Ctrl key 2 Left Alt key -> Left Ctrl key 3 Left Windows key -> Left Alt key I was using the . The first two key mapping works fine, however, the third mapping has the problem. For example, “Win+W” should suppose to map to “Alt+W” which corresponding to the “Copy” in emacs, however, it opens the “Pen” app in the Windows. I did some research, and found another tool, which called the AutoHotKey.
