And the entry you will need to set is "UseTextRecall", from "True" to "False".
If you want to set the shortcut keys to something else, then you can't use the version on Plus! website. Instead, you have to download the latest version that has "TextRecallShortcut" entry.
RE: How to disable Ctrl + Up and Down Shortcuts? (Text Recall)
The registry key is still working as intended, you just have to restart Messenger after changing it. Please see http://www.msgpluslive.net/help/registry/ for a list of registry settings compatible with Messenger Plus! Live.
Note that this option will be available back in the preferences panel in the next version of Plus!.
