Currently, in order to determine whether I want to find a phrase from the source or target segment, I have to click ctrl-f, select "Project source ...". or "Project target ...", then click "OK".
What do you think of a toggle button, e.g. where the cursor is on the enclosed drawing, and/or the corresponding keyboard shortcut?
This would speed up our work...
Why not use the dedicated keyboard shortcuts or the Quick Search Bar buttons (PR source/PR target or TM source/TM target)?
Shortcuts can be found in he Edit > Find at cursor. You can define custom values in Preferences > Keyboard shortcuts.
