I had searched by google about the question I am going to address, but still don't understand what's the solution of my case. Based on my poor language communication skill, I am showing step-by-step about my question.

  1. I have connected to a linux server, like TACC-lonestar or other RedHat/Ubuntu server.
  2. I typed "gnome-terminal" to generate a new terminal to use.
  3. on the nav-menu, I clicked the "keyboard Shortcuts" to assign a new shortcuts for copy&paste.
  4. I doubled clicked the shortcut key for copy, trying to input "Meta+C" (command+c on mac), but this input is invalid. That is, keeping showing "New accelerator..." to me. That is, "Meta+C" is not functional.

My question is I can have shortcut key for "meta+X", "meta+v", "meta+a", "meta+b" and so on. I can have shortcut keys input like "shift+meta+c." But why I am not be able to input "meta+c". In fact, before I changed the copy shortcut key, the shortcut is "meta+c". But I don't know why I am not able to do it now.

Could someone help me to solve this issue?

Thank You

    I thought that Meta mapped to the Option key, not the Command key?

    I found a solution to solve it after coupled hours test. In the preferences of XQuartz, only need to select the "Follow system keyboard layout" on the input tab. Then I can change the shortcut key by "meta+c." Hoping this is useful.

  • @Franke you can and should post that as an answer, even though you wrote the question.

I found a solution by myself. Here is the answer.

To solve this situation, you need to go to the preferences of XQuartz. After you turn on the preferences and click the "Follow system keyboard layout" on the input tab only. Once it is done, you can change the shortcut key by "meta+c."

Hoping this is useful.
