How do you reset the game to full screen?

[Mirky]

While playing CW with a full screen, the game screen suddenly shrank to a small window in the upper left corner of my screen. I probably hit a keyboard combo by accident.
I am currently unable to rest the game to full screen even after restarting it.
Does anyone know the command(s) to reset the screen? Thank You

Thank you for the information. Seems that I discovered this game years too late.
I tried the "Display zoomed-in..." instructions provided, but unfortunately my computer files are not configured the same way.
I could follow the instructions as far as: C\Program Files (x86)\Steam\steamapps\common\Return to Castle Wolfenstein - but then my computer offers me no file with the title of "WolfSp.exe" to select.
There is a file with the name shortened to "WolfSp".
When I open "WolfSp"'s Properties, my computer offers no "Compatibility tab" to select, and there is no "check Disable display" in any of the other tabs available.

I played perhaps 1/2 the game on my HP desktop running Windows 11 before this display error suddenly appeared, and am at a loss as to what brought it on.
Still, the experience was not too bad for $4.99.

Now it's called "Disable full screen optimizations", if I translate correctly

Thank you again. Here's an update with partial success.
When I reopened "WolfSp/Properties" (still no "WolfSp.exe" to be seen), to my surprise the "Sharing" tab had been replaced by a "Compatibility" tab!
There was the "Disable full screen optimizations", which I selected.
Unfortunately it had no effect. For me the game display remains small and locked in the upper left corner of my screen whether this choice is activated or not. Restarting and rebooting did not help.
There is a "Run compatibility troubleshooter" in the "Compatibility" tab, which after using had the same effect as the, "run in 640 X 480 resolution" button.
This old resolution yields some improvement, filling about 1/2 of my screen - but is not as good as the full screen I was enjoying.
Perhaps old soldier games never die, they just fade away...

Thank you again. I could and did follow these instructions precisely.
Unfortunately this also did not fix the game's sudden display problem on my computer.
I had to use "End Task" to get out of the locked-up program.
The game can still function at about 1/2 full screen size, when I use the "Run compatibility troubleshooter" in the "WolfSp" Preferences/Compatibility tab.
That is about a 10" diagonal display in actual size.
Perhaps I can press up close to my screen and finish the game.
