What is the shortcut key to select things fast in your inventory? I saw a youtube video of someone selling a bunch of things fast, but can't find it again.
The key is Alt, but you have to enable it in the game settings - apparently it's still in testing as it was found to be a bit unstable, so it's disabled by default.
Go into your game files and navigate to
[ starsector-core > data > config ] then open up "settings.json" in Notepad++ or similar. Scroll down until you find this line (line 48 I think)...
"altMouseMoveToMassTransfer":false,
... and change the value from false to true. Save and close the file, then open the game. You should now be able to hold Alt and click and drag with the mouse across your cargo to select and transfer multiple stacks of items much more easily.
How can I slow XP gain a little?
Turns out there's a config setting for this too! Pop back into settings.json as above, and scroll down to line 450:
Probably just set that to a decimal like 0.8 or something and you'll be good to go!
