How do I get the compose window in Google Inbox to go full-screen/pop out?

Previously, in Gmail, you had to (shift) click the full-screen expand icon in the upper right corner of the compose window.

However, I don't see that icon anymore in the new Inbox interface.

Holding Shift when clicking the red plus or the keyboard shortcut Shift + c doesn't work

    I'm voting to close this question because Inbox by Gmail was shut down in April, 2019, and is no longer available.

They haven't built in support for pop-out / full screen yet:


  • I'm afraid that while this used to be true, they've remedied this lack. See BioGeek's answer.

    @ale Almost, the editor is enlarged, but not full screen. How can it be full-screen or pop-out of the editor.

Since 4 March 2016, it is now possible to expand the compose window to fullscreen.

Just like in Gmail, you can now expand the compose window in Inbox. Perfect for planning an elaborate surprise 😁

This doesn't seem to have been implemented yet (opening the compose window "fullscreen" AKA in its own window), and as it seems it'll never be implemented (it's a trivial thing to implement, yet this has been requested 2 years ago / since 2014)!

What others that have responded here call "full screen", is just making a "virtual frame" within the same window bigger, that's all, which creates / doesn't solve issues associated with doing that (mainly when text-inverting), but also that you can't switch back-forward - or have on another screen in a multi-screen setup).

The best solution I've found is, to have Google Drive / Docs open in another window, then composing there in a Google Docs and then copy-pasting that into the Google Inbox reply / new mail window. Of course you can use any other text editing program or web app, but, like Inbox and Gmail, with Google Docs / Drive, changes are saved automatically to your Gmail account, which IMO is safer than using a stand-alone app.
