In the PS ISE Script Pane it would be nice if instead of having to use Ctrl+F to pop the Find window, we could just use Ctrl+F3 to search for the currently selected text. If no text is selected when Ctrl+F3 is hit, it should find the next occurrence of the word that the caret is on. This is standard in most text editors today. In PS ISE v3 we can already use F3 to move to the next occurrence, and Shift+F3 to move to the previous occurrence, which is great. This is just one of those tiny UI improvements that would make a big difference, as it removes a couple clicks/keystrokes from something we do many times everyday.
If implemented, it would make sense to also implement a "Wrap around" option as mentioned here (https://connect.microsoft.com/PowerShell/feedback/details/790583/windows-powershell-ise-add-wrap-around-option-to-find-replace-dialogues), as the "Search up" checkbox is only accessible from within the Find window.
