Changing navbar button names

[badams]

Which file contains the actual text (for the link names in navbar) so that I could change "Instant Response" to "Search" or if I wanted to capitalize the word Question in the buttons labeled "Add question" and "Open question"

Thank you

Sincerely,
Blake

Finally found it, the code for navbar button labels is inside the appropriate "language_xx.php" file in the "lang" folder if anyone else was trying to find it.
