Function Order

Hi, Since updating Draftsight to Professional last month, the order which I use to execute some functions has changes.

For example, normally when I had to delete a line I would highlight the line then press the delete key on my keyboard, but now I have to press the delete key first then highlight the lines I want to delete and then press enter. this is the case with all the modify functions and Quick Group. I am sure it is just a setting, hope someone can help.
