Mintty differs from the other tabs in that it supports xterm/xterm-256color TERM types, and does not work with ConEmu settings like color schemes and key bindings.  As such, some differences in functionality are to be expected, such as Cmder not being able to apply a system-wide configuration to it.

 Cmder by default comes with a vendored ConEmu installation as the underlying terminal emulator, as stated [here](https://conemu.github.io/en/cmder.html).
 
 However, Cmder can in fact run in a variety of other terminal emulators, and even integrated IDEs. Assuming you have the latest version of Cmder, follow the following instructions to get Cmder working with your own terminal emulator.
