Unable to setup a Keyboard action before click in one macro

Unable to setup a Keyboard action before click in one macro

Hello everyone,

I am working in AutoCAD and have about 800 arcs I need to draw. the sequence is

Keyboard   A          (Arc tool)
Keyboard Enter     (Activates the arc tool
Mouse Left click    (Start point of the arc)
Keyboard   E          (Option for next click to be the end of the arc, not center)
Keyboard Enter     (Activates end  choice)

Mouse Left Click   (End point of the arc)
Keyboard   D         (Option to chose the direction of the arc)
Keyboard Enter     (Activates choice D)
Mouse Left Click   (Sets the Arc as shown on screen)

I would have to master my time to put all that in one command. but i would like to get it down to 2 clicks.

If i set a Deep click command as 
A, Enter,left mouse click, E, enter 
Autocad should be waiting for the next click to designate the end of the arc segment.

so I could setup a button to 
left click, D, Enter
that would set the arc length and chose D for direction 
meaning I would just normal left click once more to set the arc.

but I cant seem to get it to accept an keyboard action before initiating the "Mouse Click" 

any thoughts?
