Using TAB key on selected lines of codes…

It'd be nice if you'd add a feature where you can add tab to a selected lines of code without having to move your cursor to the beginning of a line and push TAB on the virtual keyboard. It gets tiresome when you have to do that on like 10 + lines of code. Also, it'd be nice if you'd also add another feature where it'd allow us to remove the tab beside a selected lines of code.
