A look at some bundle files of the modules in this category showed that
there were usages of the 2 key/value approach for defining mnemonics, ie
FILE_Mnenonic=F
FILE_Label=File

see umbrella 86438 - direction from nb is to replace usage of
setMnemonic and setDisplayed Mnemonic to org.openide.Mnemonics
such that, instead of bundle file having a separate key/value for
defining the mnemonic key and a separate key/value for the label, that
it all be in the one key/value, for example

FILE=&File

(also, even if the assigned key is the first letter of the label, always
put in the '&')

This issue relates to all usages of the 2 key/value approach in this
category.

A quick way to look in bundle files to see this is
find <path> -name "*.properties" | xargs egrep -i '.*=.$'


If this issue needs to be filed in separate subcategories of this
category, please do so and this one could be used as an umbrella issue
of those.

I don't know if this is required to be complete for nb6; please check
with your nb team and qe on your team; the goal
is not to destabilize mnemonics since that is part of a11y criteria, but
to make it clearer and smoother for translation
teams;  based on voc and requirements from translation teams, nb team
decided to request to have these changes made.
