Once you think you've learned the easiest way to input a command or control, there seems to always be a new way! My goal is to never need to use my mouse... but that may take some time. Here's a few tips that can help!
Moving your cursor around: Use CTRL-A, E, F, B to move the cursor to the beginning, end, forward one character, or backwards. Typing clear will clear out your terminal.
Edit the text in your command: Use CTRL-D, T to delete or exchange the character at your cursor's location. Use ALT-L, U to convert characters to lowercase, or convert characters to uppercase.
Cutting and pasting: This is also called 'killing and yanking'. Use CTRL-K, U to kill text from the cursor to the end of the line or from the beginning to the cursor. Use ALT-D, and backspace to Kill text from the cursor the the end of the word or from the cursor to the beginning of the word. Use CTRL-Y to take text that has been cut and insert it at the cursor location.
We're back with keyboard shortcuts! We've already gone over the tab completion in a previous HakTip, so we'll now check out some other commands. Instead of tab, you can also use ALT-? to show a list of completions you can use, and ALT-* to insert all of those possibilities.
Check out the bash man page under Readline to see more completion commands.
