I\'m using msysgit running on Windows XP.
Tried Ctrl+V, Right click, Middle click, google... no luck.
console2 ( http://sourceforge.net/projects/console/ ) is my go to terminal front end.
it add great features like copy/paste, resizable windows, and tabs. you can also integrate as many "terminals" as you want into the app. i personally use cmd (the basic windows prompt), mingW/msysGit, and i have shortcuts for diving directly into the python and mysql interpreters.
the "shell" argument i use for git (on a win7 machine) is:
C:\Windows\SysWOW64\cmd.exe /c ""C:\Program Files (x86)\Git\bin\sh.exe" --login -i"
