Steps to reproduce the problem:
1. Go to a web page in a foreign language.
2. Visit more web pages from that page, sometimes using back button
3. Have a desire to always switch translation off or on with those pages.

What is the expected behavior?
Every page which may require translation or has used translation automatically should display the translation tool bar.

What went wrong?
After the first translated page, sometimes the page is translated but no tool bar is shown.  Sometimes it is shown.  After going back to "show original" on a web page, sometimes later pages won't offer translation.

For people who can translate somewhat, but desire help, the online translation is very useful, but we need to toggle back and forth at will.  The current interface tries very hard to guess what we want, and does a really bad job of it.  Just let us control the translation toolbar and we'll be happy.

Possible solutions, in order of preference:

1. Keyboard shortcut to toggle the translation toolbar at any time.  This would be perfect, because you could leave the rest of the code that guesses at translation preference in place and users could override as needed.

2. Turn off the guesswork.  Just always offer the toolbar on any page that might require translation, or has been translated, no matter what.  (Arguably, providing seamless translation without telling the user is a potentially bad idea.)
