Often questions can be rephrased in many (already known when asking) ways:

*How to enable GPU scaling?  

How to switch screen stretch mode?  

How to disable resolution scaling?*

Exact words may also depend on depth of user understanding of the problem.  

Tags sometimes can solve this, but that's mostly not intended use also due to their limited count. Seen opinions that placing/formulating via slash is a bad style.

Choosing just one way of all possible rephrases will probably lead to both duplicate questions and rare solutions not found by search or missed by user while checking SO Linked questions.

Is it good approach to solve this using slash/parentheses in the question itself?
