I’m not sure whether this really qualifies as an “IOS Gotcha”. It is not IOS’s fault, and only someone with fat asychronous fingers like me could trip over it.
The string I most often type when I’m doing a lab is “conf t<ENTER>”. Well, I wish it was, because very often keystrokes get transposed. Sometimes I transpose the ‘f’ and the sapce, so it comes out as “con ft”. Sometimes I traspose the ‘t’ and the <ENTER>, so it comes out as “conf <ENTER>t”. Sometimes I accidentally type it when I am already in config mode.
It’s no wonder my career as a guitarist never really took off.
Only once have I made all three mistakes in the same command.
Now, I wonder whether a config-register of 0×000f is benign …

Ahh man- you are not alone with the fumble fingers.

Good tip; I know I’ve done that. Now I’m off to SSH into all my routers and “show ver | i Config”…
