Well, many people knows the up key can search the similar command in matlab terminal. But in linux (Ubuntu), if you work on terminal and want to try this, then nothing happen. If you want it search command history automaticly, you need do:
uncomment next part:
# alternate mappings for "page up" and "page down" to search the history
Now you can use page up and down to search command history. Is that cool? eh.....
