Team Fortress 2 – The ULTIMATE Guide for Shortcuts and Tactical Jumps

Intro

In this guide, you will find shortcuts and tactical jumps to cross the map at Mach speed and to reach unexpected areas. Stairs ? What’s that ? 
 
There are all meant to be execute without any help from items or loadout, so no rocket jump, triple-jump, Powerjack, Gloves of Running Urgently … 
 
If there is any class icon on the picture, that means that this jump can only be performed by this/these class(es). Otherwise the jump can be accomplished by all classes. 
 
On symmetric maps, jumps works on both sides, except when indicated. 
 
 
 

Techniques

From the TF2 wiki 
At any point during a jump, the player may crouch by pressing the pre-assigned button. This will cause the classes to bring their legs up in world view and move an additional Hammer unit up, as well as reduce their height by 27 Hammer units from the bottom of their hitbox. This allows them to reach higher surfaces or shrink their hitboxes to dodge enemy fire. 
 

From the TF2 wiki 
Air strafing allows players to curve in mid-air to change their trajectory. Its use is to reach a destination that is hidden around a corner or barrier. While airborne, it can be performed by simultaneously strafing and turning smoothly in the same direction. Attempting to move forward with the movement keys (such as holding W) during the maneuver will prevent the player from strafing, while attempting to move backward will also result in a decrease of speed. 

From the TF2 wiki 
Surfing involves strafing into slanted walls (commonly referred to as "ramps"), causing the player to accelerate rapidly and reach an extremely high velocity. A player must strafe against these ramps using the A or D keys. 
 

Pixelwalking is an advanced technique that allows you to stand on a sloped surface, on a clipbrush or a slope.
