Clipboard contents are pasted twice

[chenmaker]

I am using arduino on mac but will paste it again when I copy it.

It's unclear what you're saying. You need to provide much more detail.

if i (command c) ---> copy print
but (command v) ---> Posted on the print will be repeated affixed twice It becomes printprint

Which version of the Arduino IDE are you using? Please test with the beta build to verify the problem has not already been fixed.

I seem to remember this having been reported previously but I can't find it. I actually did have this same problem for a while but haven't for a long time and I can't remember what changed. I do have a keyboard remapping of my copy/paste shortcuts and changed the application I use to do that at one point so it may have been caused by a bug in the previous application.

I currently use Arduino 1.8.5
I tested the problem still exists
And then you see what you say changed the shortcut key inside the thing
I would like to change (command v) to (control v or option v) one of the shortcut keys
Fantastic thing happened (command v) can be used normally but press (control v or option v) can not be used
A magical bug
I remember when I bought it (command v) can be used normally to update from a mac version to die
i buy mac in 2014 year
thank you for your help

This bug happens when your keyboard input is set to anything other than US English. It's easy to reproduce on a mac:

1. set your keyboard input to a different locale (eg: Dvorak or other languages)
2. open any sketch
3. copy some text
4. paste (Cmd-V) into the sketch.

Expected: pasting "foo"

foo

Actual:

foofoo

This bug dates back to at least April 2015, version 1.6.3:

It is extremely irritating. Of course since it mostly affects non-Americans, I guess it's pretty low on the priority list...
