Remapping keyboard keys for specific applications [closed]

Solution 1:

You can use AutoHotkey to make context-sensitive hotkeys that will work only if a certain window is active (so it will not work globally):

#IfWinActive Reminders ahk_class #32770  ; The "reminders" window in Outlook.
Enter::Send !o  ; Have an "Enter" keystroke open the selected reminder
#IfWinActive
