4.101.0.50 After + Context choice is empty

[Administrator]

Hello, I use Edit control version 4.101.0.50 with IntelliSence support. I want that context choice appears after user press + key combination in any place of editor (not after dot). I add items to list in editControl1_ContextChoiceOpen event handler. But in this case context choice appears empty and fills with values only when user press Left arrow button. Could you help?

After "Ctrl + Space"

I solve the problem.
I should have added the lexem
< lexem BeginBlock="\s" IsBeginRegex="true" Type="Whitespace" / >
into config file.
