Open another browser window.
Go into OOF and this thread (now viewing twice).
Open another OOF window and go to the cars for sale section, and start a new thread.
Go to your open window of this thread and press 'quote' and view the text box that now opens.
Drag your cursor from the start of the text (or piccy details) and out to the end.
Press and hold the ctrl button on the bottom left of the keyboard and the insert button at the same time. That copies the text onto the PC, as it were.
Go to your new car for sale post (which is still empty) and click into the text box area -0 not the header/title area.
Press and hold the shift key (the one time use capital key, not capslock) and again, the insert button at the same time. this dumps the copied text into your new box.
I have always remembered it as you want to 'contrl' what you are inserting, then 'shift' it from one place to another....
Voila, copied the info from one place to another in a couple of key presses and no extra typing!
Or, add your chosen text in a reply to this thread and possibly someone will combine/move tomorrow. If not, will do it wed evening....
