Where are Notepad++ macros stored?

If you are wondering where is the macro you just created in Notepad++ text editor, well you can find it by going to Macro -> Modify Shortcut/Delete Macro... menu option.

Once you click on Modify Shortcut/Delete Macro..., you would see Shortcut Mapper pop-up, goto Macros tab, you will see all your macros you created. You can change their name, shortcut keys and even delete them.
