The "too many items" mod jacks up chests. Turn it off, or accept the limitation.
Sometimes it is lag. But in this case, it seems like you have a block on top of your chest. If you put a block on your chest, the chest wont open.
The shift click support always stays as shift and cannot be changed.
Re instull Minecraft
I can answer this for Windows and Mac: Windows: Find your Minecraft folder (search: %appdata%\minecraft) and delete the folder named "bin". Re-open Minecraft and it will re-download the bin, fixing it. Mac: In Finder, go to your Hard drive (the silver rectangle that is named "HardDrive", users, your user name, library, Application Support, Minecraft, and delete your "bin" folder. Re-open your client and it will re-download the bin, fixing it.
You have to download the TooManyItems Mod for Minecraft. Search it up on the forums and download the ones that correspond with your minecraft version. When you update minecraft your Mods wont work because they will become and old version so wait for the mod maker to release a new version of the mod that works with the new version.
