Hot-keys

Hello, All,

I'm wondering if it's possible to bind a series of key-strokes to a hot-key.
For example, i have some very large documents to re-format, and the 
lines are very short, so to lengthen them i find it necessary to press 
<end> <space> <del>, but it's easy to mis-stroke and run words together 
or introduce unwanted double-spaces.

Can anyone tell me if it is possible to do this, and maybe - if it is - 
to give me some guidance?

Thank you.

Warmest Regards,
malcolm
