Texmaker and TeXstudio ⇒ Change the hidden Key Bindings

[eniu9350]

I'm using Texmaker for several months, but recently I found that its key binding Ctrl+Space override the operating system key binding (which is bound to the action of changing input method).

As I don't want to change the system binding, is there any way to change the texmaker key binding? (I've looked over the configuration options in texmaker, but I found only a limit amount of key bindings to change which does not contain Ctrl+Space).

In "Options" -> "Configure Texmaker" -> "Shortcuts", you'll find "Toggle focus editor/pdf viewer". It's default shortcut is Ctrl+Space.
