Refresharoo

Refresharoo lets you reload your Minecraft client on the fly — warning: it will most likely freeze or crash your game when you do. No promises on smoothness here! But if you’re daring enough to try, it’s perfect for modders and players who love tweaking without restarting the whole game. Press Insert, refresh, and keep the adventure rolling (if it works)!

Right now the key to refresh is Insert — I probably won’t change it. And honestly, if Insert bugs you, why do you bind anything to Insert???

Also, Refresharoo only reloads your client-side mods (this is a client mod), doesnt reload minecraft.

Disclaimer: Probably doesnt work, or i dont know how to test mods.
