- Ctrl + y – paste word or text that was cut using one of the deletion shortcuts (such as the one above) after the cursor
- Ctrl + xx – move between start of command line and current cursor position (and back again)
- Alt + b – move backward one word (or go to start of word the cursor is currently on)
- Alt + f – move forward one word (or go to end of word the cursor is currently on)
- Alt + d – delete to end of word starting at cursor (whole word if cursor is at the beginning of word)
- Alt + c – capitalize to end of word starting at cursor (whole word if cursor is at the beginning of word)
- Alt + u – make uppercase from cursor to end of word
- Alt + l – make lowercase from cursor to end of word

- Ctrl + t – swap character under cursor with the previous one
Command Recall Shortcuts
- Ctrl + r – search the history backwards
- Ctrl + g – escape from history searching mode
- Ctrl + p – previous command in history (i.e. walk back through the command history)
- Ctrl + n – next command in history (i.e. walk forward through the command history)
- Alt + . – use the last word of the previous command
Command Control Shortcuts
- Ctrl + l – clear the screen
- Ctrl + s – stops the output to the screen (for long running verbose command)
- Ctrl + q – allow output to the screen (if previously stopped using command above)
- Ctrl + c – terminate the command
- Ctrl + z – suspend/stop the command
Bash Bang (!) Commands
- !! - run last command
- !blah – run the most recent command that starts with ‘blah’ (e.g. !ls)
- !blah:p – print out the command that !blah would run (also adds it as the latest command in the command history)
- !$ – the last word of the previous command (same as Alt + .)
- !$:p – print out the word that !$ would substitute
- !* – the previous command except for the last word (e.g. if you type ‘find some_file.txt /‘, then !* would give you ‘find some_file.txt‘)
- !*:p – print out what !* would substitute
jQuery: Select a radio button by name and value
Using jQuery, if you want to select a specific radio button based on name and value
$(':radio[name="radioBtnName"][value="radioValue"]');Example:
<div id="radioGrps">
<div id="setOne">
<input type="radio" name="orange" value="5" />
<input type="radio" name="orange" value="10" checked />
<input type="radio" name="orange" value="20" />
</div>
<div id="setTwo">
<input type="radio" name="peach" value="10" />
<input type="radio" name="peach" value="15" />
<input type="radio" name="peach" value="20" checked />
</div>
</div>
In the above example,
if you want to select radio button in div#setOne with value 10, then
$('#setOne :radio[name="orange"][value="10"]');
or
$(':radio[name="orange"][value="10"]');
//to make it checked
$(':radio[name="orange"][value="10"]').attr('checked', 'checked');
