If you use Pe as your text editor and need to find text buried in your documents in a hurry, resist the impulse to hit the usual Alt+F. Instead, tap Alt+I to turn on incremental search, then type the first few letters of the string you’re looking for. The first found instance of that string will be highlighted in the current document. The more letters you type, the more specific your search becomes. Tap Alt+G to move to the next occurrence of the string.
Get used to this feature, and you’ll never go back to plain old Find dialogs.
