True, although depends on if you're naturally a mousey person or a keyboard/shell person.
For some reason I have an instant distrust of anything mousey - seems like a barrier between me and what is really going on. But as you say good option for those who prefer working that way :)
svn add newFiles
svn commit -m "I did something"
There's not really all that more to learn, just check the docs or "svn help" but it'll certainly be well worth your time to get into the habit.
