Steps to reproduce the problem:
1. Set Chrome's language to "español (Latinoamérica)"
2. Type a domain where you can search, like google.com
3. Look at the message on the right-hand side of the omnibox.

What is the expected behavior?
Text is "Pulsa [Tab] para buscar..." -- "Pulsa" means "press" and used to be used there, going by the screenshot at https://bugs.chromium.org/p/chromium/issues/detail?id=613776 . The user's version there (52.0.2739.0) is slightly older than mine (52.0.2743.116).

What went wrong?
Text was "Haz clic en [Pestaña] para buscar..." -- "Haz clic en" means "click on" like a mouse click.

Did this work before? Yes 52.0.2739.0

Chrome version: 52.0.2743.116  Channel: n/a
OS Version: 8350.68.0
Flash Version: Shockwave Flash 22.0 r0

Seems possible this is indirect fallout from the confusion between "tab" as in browser tab (pestaña) and "Tab" the keyboard key (Tab), discussed in 613776. That is, "Press the 'Pestaña' key" may have tripped up translators since there is no Pestaña key.
