Format bold expands to the complete document

[Stam]

When i mark a word and press the bold-button, the complete document gets
format bold. Pressing button Regret restores it to the intended format, with
the marked word in bold. Silly, and time consuming. Is there a solution,
anyone?

Also, as a matter of curiosity, in which language version is the Undo button
have a label that translates into English as "Regret"?
