I got alt-tab-macros: an awesome alt-tab application switcher for Mac OS. The reason being that I swapped my control and command keys (in System Preferences > Keyboard > Modifier keys) and I am used to the "alt-tab" shortcut.
I also started to use iTerm2, but I noticed that this new alt-tab behavior is disabled when a iTerm2 window is active.
Has anyone experienced this? Any possible solutions?
