Mac OS X Terminal shortcut keys

Terminal is one of the most frequently using application everyday but I have never had a chance to master its short keys. Today is a good day to start.

As I know, Terminal's short keys come from Emac, when I refer to meta short keys it means that you can use esc button or setting option(alt) button as a meta key. (Settings > Keyboard > Use option as meta key)

• Ctrl + a = Go to the beginning of the line
• Ctrl + e = Go to the end of the line
• Ctrl + l or Command + k = Clear screen
• Ctrl + r = Search for previous commands (pressing more r to get earlier commands)
• Ctrl + w = Delete the word before cursor
• Meta + d = Delete the word after the cursor
• Ctrl + u = Clear the line before cursor
• Ctrl + k = Clear the line after cursor
• Meta + t = Swap last 2 words before cursor
• Ctrl + d = Delete a character after cursor
• Meta + f = Move cursor to the right one word
• Meta + b = Move cursor to the left one word
