Some control+key commands on Linux shell

There are a couple I keep forgetting to remember:

ctrl-s
    freezes the screen and stops any display on the screen from continuing 
    (equivalent to a no-scroll key) (sometimes takes a moment to work) 
ctrl-q
    un-freezes the screen and lets screen display continue 
ctrl-c
    interrupts a running program 
ctrl-\
    same as ctrl-c but stronger (used when terminal doesn't respond) 
ctrl-z
    suspends a running program (use the fg command to continue the program, see section Controlling Jobs) 
ctrl-h
    deletes last character typed 
ctrl-w
    deletes last word typed 
ctrl-u
    deletes last line typed 
ctrl-r
    redraws last line typed 
ctrl-d
    ends text input for many UNIX programs, including mail and write.
