I'm a recent migrant from Thunderbird (company imposed)

After opening up a contact window, I want a simple keystroke (like
ctrl-m) to send mail to that contact.

It looks like my only options now are alt-a-m (alt, actions, mail) or
moving my hand to the mouse to click on the new message button.

I thought I could record a macro and assign it to a keystroke but it
appears that Outlook does not have a Macro record function.

Any suggestions?

TIA,
Mark
