How do I change script API reference language in Monodevelop?

When I use Ctrl+’ in monodevelop, it tries to search manual in russian. Is there a way to switch language to english somewhere in monodevelop? Because most pages just do not exist in russian.

Accidentally found an offhand solution myself. Just switch language in the browser, when surfing Unity3d.com site. Even if it’s in English, switch to other language and then back to En. After that using Ctrl+’ in monodevelop will bring English manual and scripting references.

Maybe it was kinda obvious, come to think of it - apparently “help reference” chooses a language based on browser settings. But still, noone managed to tell me. (
