the linux terminal remembers all the commands you have wrote before, just press the "up" key
- Extra Button & extra buffer
i was always wondring when i c a type of mice that contains 3 buttons, what is the middle button for, or why isn't it used it seems that Ubuntu Developers heared my thoughts :D in Ubuntu there is two clipboard buffers which means you can copy two distinct text portions in the same time one of them is accessed with the normal methods "Ctrl+C" of "RMB -> Copy" and the other clipboard buffer is accessed with the third
mouse button or the wheel button ,press on the mouse wheel when selecting the text and it will be copied and when u need to paste press the wheel again i like that feature (Y)
- Copy Path
sometimes you need to copy the file path well, in Ubuntu you can RMB on the file and copy it then go to any text area and paste, the file path will be pasted 3-On line :D
