Scroll wheel, so I don't have to take my fingers off the WASD keys.

My mouse wheel up/down/click are primary/secondary/melee, respectively. I switch the latter around if a different configuration makes more sense for a specific class (spy is primary/melee/sapper, engie is primary/melee/secondary, medic is secondary/primary/melee). Configs rule.

Each mouse button switches to and fires a different weapon. Mouse1 for primary, mouse2 for secondary, mouse4 for melee. Mouse3 is bound to +attack2. This way, I don't have to use any brainwork to figure out which weapon I'm on and how to get to the weapon I want. It's also very convenient for crosshair switching and turning on/off view models for particular weapons.

Q is primary, E is secondary, melee is 3

I always used Q, E, F I find it more confortable than using 1,2,3 or the mouse buttons even.

i scroll then click once the weapon i want is selected on the side of the screen :D

scroll wheel

Wow nobody has said the default 1,2,3,4 yet. I like it allows me to rapidly spam weapons

m4 primary, m5 secondary, m3 melee

1/2/3/4, tried using mwheelup/down/mouse3 but it never felt natural. occasionally have to do finger gymnastics to strafe and switch weapons but w/e

q primary
w secondary
a melee
t pda1
5 destroy building
(esdf)

i use autohotkey and i have to type in ctrl+478 to go to primary or ctrl+990 for my secondary and F for my melee

I used to just use the mouse wheel but it felt a bit slow so I just use the number keys now

i use mouse4 for primary, mouse5 for secondary, and r for melee

shift-primary
q-secondary
f-melee

My Q button scrolls between primary and secondary weapons, 1,2 and 3 are bound to their default values.

1 primary
2 secondary
3 melee
q lastinv

q switches between primary and secondary. 3 for melee

123 i have Q bound to mask call and e to +attack2

MW up primary
MW down melee
F secondary

Hold right click - switches to shotgun / pistol
Release right click - switches back to primary.
Middle mouse button - melee

Some say it's dumb but I find I actually grip the mouse better while holding rmb.

I probably have the weirdest binds ever.
C - meele
B - secondary
Mouse1 - primary

V is attack, jump is shift.

this got downvoted but to clarify i like this because using 1, 2, 3, 4 inhibits movement as you cannot hold w/d and switch weapons at the same time

Scroll wheel -
Up = primary
Down = secondary
Press = melee

1,2,3

I use a combination - I always press 2 to switch back to medigun, for instance, but scrollwheel for crossbow/ubersaw. I would love a new melee bind,, I've found that occasionally when switching to melee I accidentally scroll up/down and this weird thing happens where melee is out/away/out/shit I'm dead

I used to use mwheelup for primary, mwheeldown for secondary, and mouse3 for melee but I broke two scroll wheels doing that (Zowie scroll wheels are trash tho so i don't know if decent wheels would have broken) because I scroll really hard and I'd spam weapon switch a lot.

I switched to q for primary, e for secondary, and r for melee and I like it better.

q to swap between primary+secondary, 3 for melee

i used to have this then my intellimouse middle click broke so now i use R for melee
