How do I allow the mouse to escape borderless window?

[madamepestilence]

I'm aware that this isn't something that can be done normally with specifically Skyrim for some reason (as well as disabling the windows key, meaning the only way to escape the window in vanilla afaik is to close it or alt+tab), but I'm used to the PS4 version of S:SE and I'm unclear on the modding process.

If a mod exists to allow the mouse to leave the borderless window when in menus, information on what mod it is and how to use mods in the Steam version would be greatly appreciated. The fact that even TF2 lets me do that and S:SE won't is baffling.

The "SSE Display Tweaks" mod might help, I remember seeing an option that supposedly locks/unlocks the mouse cursor in the active window.

Unmodded, not sure.

I dont have a MOD, my mouse do's it automatically, If i'm watching summit, an I scroll though a Shopkeep in Skyrim, it either mutes my volume, or turns it down.

just alt-tab...

because if it's borderless windowed, you can't LEAVE borderless windowed mode if that is what's on top, as it's borderless, edge-to-edge, your mouse is set for input for this on-top app...

and if not, well, most people WANT window locking because it's insanely annoying for input to stop just because you rolled your cursor past the dimensions of the window, in regular windowed mode...

again, just alt-tab.
