Cell macro button

Some stuff gets done a lot, the same way, over and over, on cell phones. Like texting the person you are picking up "I'm on the way". These things could be automated.

I propose the cell phone have a macro button. The macro then walks thru launching the app, entering text, sending etc. For a small number of macros you could press the button itself 1 or more times to launch the corresponding macro. For example I press twice to text my daughter "I'm on the way". I press once to text "I am waiting outside". Etc.

A physical button would be good because the phone could stay in your pocket. More complex macros could have the macrobutton and a character key, which would involve looking at the phone (which I want to sidestep).
