Editing Scanco Administration (section)

====Keyboard Shortcuts====

Here are some common command line keyboard shortcuts.  Some of these are bash-specific shortcuts, so not all of them will work on all systems.

Note: If you're using OS-X, a number of the editing shortcuts below work in ALL programs in OS-X.  (With the sad exception of Microsoft Office, which overrides the system-wide key bindings.)

{|
|+ Table 1. Common editing key bindings
|-
|width="80pt"| <tt>CTRL-A</tt> || Move to the end of the line.
|-
| <tt>CTRL-E</tt> || Move to the beginning of the line.
|-
| <tt>CTRL-F</tt> || Move forward one character.
|-
| <tt>CTRL-B</tt> || Move backward one character.
|-
| <tt>ALT-F</tt> || Move forward one word.
|-
| <tt>ALT-B</tt> || Move backward one word.
|-
| <tt>CTRL-D</tt> || Delete one character forward.
|-
| <tt>CTRL-H</tt> || Delete one character backward.
|-
| <tt>ALT-D</tt> || Delete one word forward.
|-
| <tt>CTRL-W</tt> || Delete one word backwards.
|-

|}

{|
|+ Table 2. Common control key bindings
|width="80pt"| <tt>CTRL-C</tt> || Terminate the current program, or sometimes cancel some operation.
|-
| <tt>CTRL-\</tt> || Seriously kill the current program! Use only after <tt>CTRL-C</tt> has failed.
|-
| <tt>CTRL-D</tt> || End-of-file. This is often used to signal the end of input, or to exit a program.
|-
| <tt>CTRL-G</tt> || Cancel the current operation. An occasionally useful command to get yourself out of things.
|-
| <tt>CTRL-L</tt> || Redraw the console. Mostly useful if some program running in the background spews a lot of stuff onto your terminal.
|-
| <tt>CTRL-Q</tt> || The only time you need this is if you accidently hit <tt>CTRL-S</tt>. In that case the console is locked until you hit CTRL-Q to unlock it. Apparently once a long long time ago this was actually a useful feature.
|-
| <tt>CTRL-R</tt> || Recall command containing characters. After hitting <tt>CTRL-R</tt>, type the fragment you want to search for. If it returns a command which isn't the one one want, hit <tt>CTRL-R</tt> again to cycle through matches.
|-
| <tt>CTRL-Z</tt> || Suspend the current program and put it in the background. This is very useful once you figure out how it works. Refer to the section on putting jobs in the background.
