First of all, here's a couple things I found while messing around with this game.

Second of all, how does the Mission List Glitch work? I'm not sure what inputs are being done to warp to objectives like that.

To use Mission List Glitch, you need to move the pointer over the mission to which you want to teleport, then press the enter 2 times and 2 times the space

i don't know exactly how it works
By iteration, I found that the minimum number of clicks is 2 times enter, 2 times a space
You can do 5 times enter and 2 times a space, and it will work
You cannot do 1 enter and 2 times a space, will not work

the glitches that you found are known for a long time and do not help the passage in any way, as far as I know
