Typing 'n' character while entering filter text opens the new post dialog

[jship]

While entering the text for a filter, e.g. if I wanted to look for posts with new in the title, as soon as I type the n character, the dialog for creating a new post opens.

The filter searching is case-insensitive, so this issue can be worked around by typing capital N instead of n, and entry of the filter text can continue.
