Go there ^^^^^^^^ (NOT MY MOD)
**Edit: also fixes being able to cancel out of reading a book**
Download v3 (May not be needed, but you do need to create the folders described by mod poster (Controls and PC))
Download SkyrimKeyHelper_1000 (Bottom of download page... for me anyway...)
Do the following
Live life again!

This may work for other button problems, however these were the only ones that I was having trouble with. Definitely give it a shot though with any other problematic buttons.

This was really pissing me off so I hope it helps some people.
After patch 1.2 I was having strange problems with the key mappings. For example the in the map, the left mouse button would close the map instead of place a marker, the tab button would not longer cancel out of the map, and if I were to press P to place a marker, then press P again to remove it, I could not click anywhere and the game was essentially locked to the Move it, Replace it, or Remove it screen no matter what button i pressed. Also i was not able to TAB out of lockpicking, therefore forcing me to open a lock or quit the game.
After playing with the custom Skyrim Key Helper program provided, I was able to fix all of it.
1. Go into the Skyrim Key Helper and navigate to Map Menu from the drop down.
2. Go to PlacePlayerMarker and add Mouse1 (or personal pref) to the list. I also kept P on the keyboard list.
3. Also, I don't know if this actually does anything but I went to the Cancel option and reselected and added Tab just in case.
4. I did the same as step 3 for other various options (pretty much every choice in the drop down menu) for mainly tab and Mouse1 throughout the controls just in case... not sure if necessary.
5. Set any other key bindings the way you like...
6. Click Save & Write Changes (Will probably need to create the folders Controls and PC as described by crazygNexus)
I think that's it guys... I hope it helps you because it made the patch much more bearable for me... that was the only glitch I've actually faced post patch.
