player.modav carryweight XX - where XX is the amount by which you wish to increase your carrying capacity; e.g. if your current weight limit is 300 and you wish to raise it to 1000, use a value of 700.
player.setcrimegold XXX - Set it high if you want to fight, set it at 0 if you want to be free.
player.setlevel X - Make X equal your desired character level.
player.setav speedmult X - Where X equals your movement speed in a percentage value. (100 = 100%)
player.setav skill X - Sets skill without messing with level gains. The skill name can be found from the skill list, and X equals the value you want that skill to be.
This also works for health, stamina, magicka, and carryweight. Example: [player.setav marksman 50] sets your archery to 50.
player.modav skill X - Buffs or debuffs a skill. The skill name can be found from the skill list, and X equals the value you want that skill to be.
Example: If your Block skill is 30, you can "player.modav block 10", activating a buff to your Block and setting it to 40 (with the skill level appearing green as if a spell or item is affecting the skill).
The same can be done in reversing by using a negative integer. Using "player.modav block -10" would activate a permanent debuff to your Block and set it to 10 (with the skill level appearing in red).

Other Codes
movetoqt - teleports you to quest target (currently not working for me, but is recognised by console.It will only work on quests with target markers, Bethesda quests;
will not work on side quests with the new variable target locations.)
AdvSkill - Give the player the desired amount of skill usage points [AdvSkill onehanded 100] (after some testing the number placed at the end of the command would indicate usage points, not skill points.
For example: if you used advskill onehanded 100, it would be the equivalent of 100 swings of a one handed sword, not 100 skill points.) Skill list
IncPCS - Increase the players skill points by one point [IncSkill onehanded] - Skill List
player.modav carryweight ## - Adds amount to weight limit (Can also use health or magicka or stamina instead of carryweight to increase those totals.)
PSB - Adds every spell
qqq - quits the game without exiting to the main menu.
unlock - Target the desired chest or door by clicking on it and then type "unlock"
lock XXX - You can lock chests and door, or people by targeting them and typing "lock" followed by the level of difficulty you wish to set it at.
kill - Target your enemy by clicking on them once in the console menu and type "kill" and it does just that.

ressurect - Killed someone you didn't mean to? Target them once in the console menu and type "ressurect" and it will bring them back from the grave.
