RUN keyboard shortcut - context aware

I have set up a custom keyboard shortcut for Run, Run Selection, and Run current query, thusly:

You can see I have F5 linked to all 3, which [I know] doesn't really make sense. But what I'm trying to achieve is behavior similar to MySQL Workbench and SQL Server Management Studio - which is this:

• If you don't select/highlight anything, and run the query, it will run ALL STATEMENTS in the window.
• If you select/highlight any statement and run the query, it will run only that statement.

By default, HeidiSQL doesn't seem to work that way, so I went down this path of setting custom keyboard shortcuts.

So to my question: How do I set my F5 keystroke shortcut such that when nothing is selected/highlighted, it executes all statements in the query window? And when I highlight a statement and hit F5, it executes only what is highlighted?

Thank you in advance for advice.

One important point I forgot to mention: I want "run everything" and "run highlighted" both linked to the F5 shortcut. I do not want a different shortcut for each. This is how MySQL Workbench and SSMS work by default.

Such a context sensitive action is not yet supported by HeidiSQL.

At least for the "Run current query", this would also make no sense, as it is impossible to know whether the user wants to run all or one query.
