Fusion 360 - using last command again

[dan.bedore]

when drawing a line sometimes I can keep using the line command after clicking and sometimes I can't. I believe that there are some keystrokes that will allow me to reuse the last command.

When sketching a line the rule is that the line continues, from point to point, until you either click on an existing sketch object or you select the circle with a check in it.  If you want to repeat a command by right clicking and selecting the Repeat Line or whatever command you just executed.  One advantage to using the circle with the check is it stops the current line but keeps you in the line command.
