Hidden Shortcut in Grub
Many people are using Ubuntu nowadays and almost all ubuntu users also have windows installed.
To load your choice of operating system a boot manager is used.In the above case the Grub boot manager which comes along with Ubuntu is used to select the operating system to load.The boot manager displays a menu which lists installed operating systems.We use the up and down arrow keys to navigate the menu and the Enter key to select our choice.
Once by mistake I pressed the right arrow key and the current selection was loaded.I tried it once again and found that the right selection key is equivalent to the Enter key in the navigation menu.This can be handy for lazy users.They need not move their hand to press the enter key.
If you have any use for this hidden shortcut key please reply.
