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.

[chenmaker]

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

[per1234]

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

same problem, basically the txt editor read my short cut key twice when i do it once, also happen with Cmd+/, it comment out and then back the line

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...

I have this problem still.... here is my solution.. PASTE (cmd-v) gets you two copies.... UNDO (cmd-z) removes the 2nd copy only.... inelegant but it works for me.

I have same issue. When I have russian keyboard layout

[wtrout]

I'm a DVORAK (QWERTY commands) user who just switched to mac. Dang this bug is annoying.

A further note on gweep's post: undo (cmd-z) goes through twice so that trick doesn't work for me.

[auxiliaryjoel]

does anyone have a soluation for this. I screenshot items to my clipboard constantly as part of training for my clients,
in the past pasting this content behaved as it should - it would only paste the screenshot once into my gmail emails.
But in the last month or so that has changes to now always pasting the screenshots 2 at a time.
What on earth has changed? (Mac OS 10.14.6 on Imac)

[dderg]

same for me, and I thought it has nothing to do with Dvorak I use because I tried Russian to check - but appears they are both broken...

[mknippen]

+1, I can confirm that this is still an issue in 2022 with the latest build (1.8.19) for Mac on a Dvorak keyboard.

[mertnesvat]

yep it's related to the keyboard layout in Dvorak it's double pasting but USA keyboard works fine.

[gweep]

Holy cow! How long is this going to remain unaddressed?

[per1234]

There is a good chance it already has been addressed. Please check to see whether it still occurs with the latest nightly build of Arduino IDE 2.x:

https://www.arduino.cc/en/software#nightly-builds

[zaneclaes]

@per1234 if you look just above your post, you'll see that someone tested the nightly build just 4 days before your post. Some of us have been repeatedly reporting this issue for over 3 years now.

The problem has actually gotten MUCH worse after the latest nightly build and the switch to Arduino IDE. Now, the hotkeys do something completely different. For example, if I press CMD+C (using Dvorak+QWERTY) to copy something, it instead makes the Output tab disappear (and does not copy anything). If I press CMD+V (to paste), it says CMD+K was pressed, waiting for more keys (and again does not actually do anything).
