Call context helper immediately by shortcut

Is your feature request related to a problem? Please describe:
When I move cursor to place, where is dot(.) is last symbol, I want to see context helper.

Describe the solution you'd like:
Call by shortcut, for example - Ctrl + Space, as in IntelliJ.

Describe alternatives you've considered:
Auto show

Cursor in the end of line
*click Ctrl + Space*

No files, tests, or entry points are named in the issue. Start by locating the Unreal Engine editor code that handles the context helper and keyboard input, then determine where Ctrl+Space can trigger it when the cursor follows a dot; done means the shortcut opens the requested context suggestions in that position.
