As a new or experience CAD user, you might found that GstarCAD has a lot of commands. Not to mention changing the system variables. Some (well, many…) of them have to be activated from command line.

It is very difficult to remember all of them. Even for experienced users. Don’t worry, you can just type first one or two characters, and cycle between those commands!

For example, type two characters like ‘re’ to find out what commands started with them. Then press down arrow, keep pressing for several times. You will see the commands cycling in the dynamic input.
