The gnome-terminal doesn't store the "Select-by-word characters" preference when it is changes from the preferences dialog. To replicate: 1. start a gnome-terminal 2. right click on terminal to bring up context menu 3. Select 'Preferences...' 4. Add an underscore to the beginning of the "Select-by-word" characters. 5. Click "OK" 6. Exit the gnome terminal 7. Repeat steps 1 through 3 The underscore that was added in step 4 has not been saved.
hmmm - actually gnome-terminal seems to ignore the contents of "wordclass" in .gnome/Terminal altogether. Even with an empty "wordclass=" line in the config it still uses the default word chars.
This appears to be fixed in gnome-core-1.2.4-3 (although I can confirm seeing it in the stock 7.0 gnome-terminal)
