I recently migrated this blog from Blogger, which was posting via SFTP to a shared hosting provider, to a self-managed Typo installation. One of the biggest reasons I didn't do this sooner was that I didn't want all of my old URLs (and the links that point to them) to stop working. After all, what is the point of a permalink if it stops working one day? It isn't that I have such high page rank with Google or anything, but I didn't want to have to start over from scratch.
I wanted to be sure that if someone either typed in a URL that used to work, or followed a link from an outside page, they would end viewing the content that they expected to land on. I thought some about having some kind of logging, so I can be aware of when people use these old links, and where they are coming from. I also thought about having some mechanism for alerting the user that the link they followed is old.
Customize Firebug shortcut keys
However, these keys are not configurable. They may conflict with other shortcut keys in your system. They may not be the same as other keys you have already learned (eg, the keys in Eclipse). In my case, I found myself reaching for F5 - F8, which are the shortcut keys for Eclipse. Also, the Firebug keys conflict with the default Exposé keys in OS X. (Yes, I know I could change those shortcuts, but I've grown accustomed to their defaults.)
