There might be a number of situations when the whole text of the current segment’s source is needed for something other than translation itself: performing concordance or web search, writing a translation note in another application, asking your client or project manager about the text, etc.

Currently, in OmegaT it can be achieved in several fairly easy ways:

• Selecting the text with the mouse (but who wants to do that?)
• Inserting the source text into the target area (Ctrl+Shift+I or Ctrl+Shift+R) and selecting the text there
• Unlocking the text caret with F2, and then using arrow buttons and Shift to select the text
  (If you want to have the caret unlocked by default when you start OmegaT, there’s a way to do it)

All that is fine, but it would be much nicer to have a simple shortcut to select that source text, similar to what Ctrl+A does (which in OmegaT Editor selects everything only in the target field, or the complete textual contents of other panes if the got focus). I’ve written a simple script that does just that, and though scripts can be bound only to Ctrl+Shift+F[1-12] keys, it’s better than not having a shortcut at all. Hopefully, this function might appear in OmegaT itself, but before it happened, here you have it:
Get it from SF.net
Get it from GitHub

Happy selecting!
