I searched on this topic and haven't found an answer to the question of whether this bug has ever been addressed.  It's the main reason I stopped using SONAR (15-year user).
 
I couldn't find a demo of X3 to test this.

I just tried to save a patch using Zebra and it seems the Sonar GUI still intercepts the keys and executes them as shortcut actions.
 
Clicking 'Give all keystrokes to VST' does not help.
 
As you point out, this has been around for a long time.

It sucks, but my work around for this is to open Notepad or some other word editing application, write out what I want in the application, then copy and paste it into Sonar wherever it is needed.  This has worked so far for me.
 

When I'm creating patches for Zebra, I'm usually running it standalone rather than inside SONAR. In this mode, there's no problem typing into dialogs.

It would be nice to have an on/off switch for temporarily disabling hot keys... seems a simple fix to a periodically aggravating user interface issue...
I do the same as bit, or when activating synths copy/past from email...

Would somebody mind listing the actual steps to repro ideally with a synth bundled with Sonar? Please leave nothing out from creating a new project (do it in a list fashion). Thanks.

I think this is actually partially an issue with some U-he vsts - I thought I read that they were intending to fix it soon, but that was a couple of months ago I think.

It also occurs with a few other companies' synths as well.  The Notepad workaround is a kludge.
 
As far as I know, U-He synths don't operate in standalone mode.  How'd you manage that?
 
I agree, a simple way to turn off the default hotkeys would do it, basically make the existing preference settings work, which they never have, and after years of complaining about it, apparently never will.
 
Thanks for the responses, you answered my question.

I use a host called SAVIHost. It'll let you run any soft synth standalone. I was tipped off to it in the Spectrasonics documenation (Omnisphere has no standalone mode, either).
 

The Notepad trick might be a Kludge, but at least it works when you are in the middle of your project.  Take it or leave it.
