Touchy

With the current release Wheezy what do you use for an editor. On the Ubuntu versions we used gedit which would allow you to reload the tool table to make sure that tool length was picked up.

Mousepad comes with the Linuxcnc Wheezy ISO. But you can download and install any text editor of your choosing via Synaptic (including Gedit).

Even in debian xfce interface?

Yep, it can be done, but adding Gedit will require installing a rather large pile of Gnome dependency crap (Synaptic should take care of it automatically.)

So if this computer has no internet connection there is not alot I can do?

If you don't like Mousepad, it is possible to download the files on another PC and install them from a flash drive or something. But sometimes it is just simpler to unplug the PC and carry it to where you can plug it into the internet, install the software (and make any other updates) then drag it back to the machine.
