Can i view and edit values of G54,G55 etc?

I am a noob using axis GUI and wanted to know if the values of G54,G55... Offse values can be viewed in a table or atleast edited in some way. I ask because i use this in fanuc systems.
Thanks in advance.

You can view them by looking at the associated parameters. I think that the parameters listed there are read-only, but it is a fairly quick experiment to find out.
Or you can see them in some GUI screens if you turn on the full DRO
You can set the parameters in a variety of ways with the G10 commands from MDI.
The offsets are stored in thelinuxcnc.var file (or whatever your .var file is called in your config) and an be edited there with a text editor, but you would need to make the edits with LinuxCNC not running, or your edits would be over-written on exit.

I think he wants (and I think it would be nice touch as well) something like the tool table editor where he can view and modify all the work coordinate settings.
similar to these screens used by Fanuc controls

I think most of the glade based UIs have something at least sort of equivalent.

I had the idea of embedding a gladevcp tab in axis using the offsetpage widget like what is used with Gscreen (and I think Gmoccapy.) but I'm having trouble making it work.
