can i create a hotkey that executes keystrokes?

i want to hotkey change to a different periodicity for the selected chart

can i create a hotkey that contains the keystrokes "enter" and "m" and "5"?

i'm aware the the outside program AUTOHOTKEY but can it be done within MT4?

thankyou

Apart from (1) the ability to call menu options with individual keystrokes (e.g. load a template with Alt-C T etc), and (2) assign a hotkey to run a script, indicator etc (right click on the indy from the Navigator and select 'Set hotkey'), you can't assign hotkeys within MT4. You need third party software like Autohotkey, just like you said. At least, that's as far as I know.
