Hi Stien, welcome to MoI and to the forum!

Yes, it is possible to set up a hotkey to do a specific Align mode.

The way it works is to put a parameter value in the shortcut key, with a space character in between the 'Align' command name and the parameter. The parameters for the Align command can be one of: HorizontalCenter, HorizontalTop, HorizontalBottom, VerticalCenter, VerticalLeft, VerticalRight .

So your shortcut key set up would look like this for example:

A=Align HorizontalTop

Hope that does what you wanted! - Michael
