Abbreviation for Circle, Point, Angles

Is there an abbreviation for "Circle, Point, Angles"? I'm a long-time (now ex) Autocad user and I prefer to type rather than wander around the screen to click on the odd icon.

yes. https://librecad.readthedocs.io/en/latest/guides/cmdline.html

 I'm in that same boat! Try this link.

Also have a look at Drawing Tools in the manual.  The Command column lists what commands are available.

In the manual I am using (LibreCAD 2.1.3) it says:

 1.1 Curve, Point, Angles
Commands: a, arc
Prompts:
“Specify startpoint or [center]”
“Specify radius”
“Specify start angle”
“Specify end angle or (angle/chord length)”

yet instead of prompting for radius, it prompts for "Specify second point", not the same as the Icon in the first position of the toolbar in the lower row. In addition, I cannot find a command name for the Icon in question. With that, I could create an alias—providing me with the abbreviation of my choice.
