How to change keyboard shortcut to switch input language on Chrome OS?

Question

On Chrome OS, ctrl + space is used to change current keyboard layout.

This is very inconvenient when using a computer for programming. Usually, this keyboard shortcut is triggers the help popup. For example IntelliSense features in VS Code or QtCreator's completion. Is it possible to change the shortcut key to shift + alt?

Has anyone created a petition to add missing features to the Chrome OS keyboard software? Is there a user-friendly solution to the problem (command for crosh without creating your own Chromium OS distribution)?

Pressing ctrl + shift + space does not solve the problem.

UPDATE:

Damn It! Currently I am living in 2021 and they created tumbler to remap the backspace button into Google Assistant trigger, but feature with custom shortcut for keyboard layout switch still is not resolved

On emacs this is an issue too, as ctrl+space is used for another frequently used function (setting regional mark). Just as a pointer, I'm logging toward my own solution (my setup may be a bit more complicated as it entails Linux mode on ChromeOS) in github.com/kinu-garage/hut_10sqft/issues/926 – Hara

@Hara Nope, this is ChromeOS specific behavior. For example, VS Code will not interrupt the Ctrl+Shift hotkey on Windows and will switch the keyboard layout correctly. – Gerick

Sorry, I should've mentioned "emacs on ChromeOS" (I cannot modify my comment as certain time passed). – Hara
