Xshell break When selected text is copied
In Xshell set the "Automatically copy selected text to the Pasteboard", has not been a problem, recently found that as long as the text on the screen, copied, but the shell terminal was immediately interrupted, that is, sent to the terminal ctrl-c;
Reason:
It is likely that "selected copy of text" Conflicts with the dictionary software's "word translation". My reason is that I recently installed the Bing Dictionary and turned on the "word translation" feature.
When I asked for help on the Internet, I found that some friends had the same problem as me, because of the conflict with the dictionary, such as Youdao dictionary, turn off the translation function.
Install PowerWord same has similar problems. Cancel out the "translation", the small hook can be.
Turn: Xshell Mouse selected, terminal immediate interrupt (CTRL-C) problem
