Well this post is inspired by a bug post I saw earlier - just wanted to post some minor tips and tricks for Underrail. Please add your own below!
F1 will bring up the interface help screen, but it doesn't tell you you can just hit "enter" key to manually start combat.

http://isometricland.net/keyboard/chart-underrail.php?gam=120&sty=15&lay=1 - keyboard command chart
Looting screen - Right mouse click on an item to instantly loot a single item, "a" key to loot all, Alt + click = transfer item between screens
Inventory screen - Right mouse click then left mouse click on a loaded weapon to unload its ammo. Remember when you recycle a loaded gun you'll lose those ammo. Ctrl + click = instant equip item
Crafting screen - clicking on the crafting component square will auto-scroll through all available components. Ctrl + click will select specific component.
Pickpocketing screen - Alt + click = pickpocket item
Currency exchange - Colton in Junkyard is a ripoff, just exchange your SGS credit w/ Blaine/Jack Quicksilver/Old Jonas to Charons using normal trade.
Want to run faster without using cheat engine? Use Sprint outside of combat and/or wear high grade Infused Cave Hopper Leather armor + tabi/boot w/ boot spring.
If you have high enough bio you can carry ampules and convert organs into useful chem which is far lighter.
Infused pig leather boots increase carry capacity by 30, rathound BBQ adds 1 STR, powerfist adds 1 STR, rathound regalia adds 1 STR - so you can increase your carry capacity by 60 minus their respective weight. Or just use Cheat engine.
No one will buy the following items: throwing knives, throwing net, and bolt trigger.
