Allow user to move caret to end of a line or its beginning

[rm-code]

On Windows the user can press the 'home' or 'end' key to jump around. On OSX he has to use cmd+arrow keys to move around.

If the user holds down shift while performing the above operations the whole line will be selected from where the caret was currently placed.

Very nice.

@rm-code, quick question. On most non-Mac systems I've seen, ctrl-left and ctrl-right move the caret one word at a time, and ctrl-shift-left and ctrl-shift-left move the end of the selection range one word at a time (see bottom of #23). What's the usual key combo for this on Mac?

[rm-code]

On OSX you'd usually use the alt- (also know as "option"-) key to move one word at a time. Same goes for moving the selection (alt-shift-left / right).

I've actually been working on this, but it didn't turn out as good as I wanted it to be :grin:

Basically tried it like this:

local function jumpWordLeft (self, alterRange)
    trimRange(self)
    local text, endIndex = self.value:reverse(), self.endIndex
    local pos = text:find('%s', #text - endIndex + 1)
    if pos then
        selectRange(self, not alterRange and #text - pos, #text - pos)
    end
end

I guess looking for non-whitespace chars would've made more sense ^^

I also couldn't decide whether to break words only on whitespace, or on any non-alphanumeric character. I've seen both behaviors and I'm not sure which I prefer. I guess either behavior is better than nothing, though. I'll take a closer look at your solution when I get a chance :)
