Every time I need to use one during flight, I have to look it up on my printed sheets - 4 pages of them printed back to back - and it takes an age. Sometimes, long after I've passed the position I've needed it for!

Ok - I know I can pause the flight while I look it up but that rather takes away the sponteneity of the thing.
Also, what is the quickest way anyone has found for me to change a flight from VFR to IFR or the reverse? There seems to be no hotkey for it.
