repeating the same type of action on a different point/surface/vertex

You are talking about something like a script/macro commands. That is something that come time to time in discussion, but never was really implemented.

There is an external script tool that can be used for batch processing files. It's a command line available in the Wings3D install dir.

I see a problem in that because for many commands you need more than a selection as input - you may need to inform a position, an angle, a vector, ...
I see that as hard to handle since the user will need to be prompt to enter these information.

and when I see this suggestion:

1) select the features that need to be changed
2) on the keyboard, hit the following sequence of keys:

mpz

m stands for move, p for plannar, z for.. well z is z.

3) move the features around.

you have to agree you are going to do exactly these steps when you are using hotkeys: select something, hit the hotkey for each command and input the parameters as needed.
In this case, you just need to assume you have to assign those keys for each command you mentioned.
