I'm an ex-autocad user familiar with using right click as Enter. The preferences allow various customisations and i've found the right combination of check boxes to allow this. 

One area it doesn't seem to apply is using the offset function:

type 'O',

right click,

type offset distance (example 12mm)

right click,

Unfortunately it doesn't recognise the second right click and the line is offset by the default distance. To make the offset distance work I have to hit Enter.

Is there a setting to change this, or can it be fixed relatively easily?

Kind Regards,

Luke
