The missing buttons on OS X

I always wondered Windows computers have dedicated [Home] and [End] button, where are the same for Macs? Here it is, some quite useful shortcuts on Mac OS X:
CMD + LEFT ARROW = HOME
CMD + RIGHT ARROW = END
CMD + SHIFT + LEFT ARROW = Select from current position to the first letter of the line
CMD + SHIFT + RIGHT ARROW = Select from current position to the last letter of the line
CMD + LEFT ARROW then CMD + SHIFT + RIGHT ARROW = Select the whole line
OPT + LEFT ARROW = Jump to the last word
OPT + RIGHT ARROW = Jump to the next word

Which holding the shift key will select whatever you want. I found these are very useful, especially when used with MySQL development.
