Guild Wars 2

Is there a keyboard command to sheathe/unsheathe weapons?

After combat there is often a long delay before weapons are auto-sheathed, which slows down my running (or, as a Charr, my leaping) and I’d prefer to have a choice, if possible.

You can set one. There is not one by default.

You can bind it in the keybindings menu under Options.

Also, your leaping is only slowed when you’re in combat – is the area around your ability bar glowing slightly or is it completely clear? If it has a glow/effect around it then the game is still registering you as in combat (perhaps you still have a condition on you), if not then whether your weapon is sheathed or unsheathed will make no difference to your jumping
