I already knew that Ctrl+Shift+u would allow to type a character by giving its Unicode hexadecimal representation: an underlined u appears, you type the code and hit Enter.

For example, Ctrl+Shift+u; e; 9; Enter gives the character é.

Now I've just noticed that Ctrl+Shift+e lets an underline e appear, in a very similar manner, but I can't figure out what it does.

Does someone know? Thank you in advance.

Ctrl+Shift+e is the emoji entry shortcut/hotkey sequence.

It produces an underlined "e̲", if you type "joy" after it (so it looks like "e̲j̲o̲y̲") the whole word will be underlined. On pressing a whitespace entry key, like spacebar, you should then get the "e̲j̲o̲y̲" text changed to "😂" (the emoji character selected by your current application). 👍

    I think you can adapt this to a separate answer to this question too.

    I can't find a list of codes anywhere, happened on the "joy" one. Apparently the emojis are based on EmojiOne and I thought based on that linked page that the shortcode without the separators would be the entry code, but only "joy", "kiss" and "like" works for me. "grinning", "smile", "frown", "sad", "couplekiss" etc. as modifiers after the shortcut don't work, they give no entry. Links from bugs show you can disable it with ibus-setup, but I don't have ibus installed on my Kubuntu.

    I think simple simple emoticons (e.g. :) :( :p :D etc.) may work, please try them. I don't have a 18.04 installation with me right now.

    Thank you! Now can we disable it? 😂 It conflicts with IDEA/Android Studio's shortcut for Recently Changed Files.

    @Peter You can disable it by launching IBus Preferences -> Emoji tab -> Emoji Annotation -> ... -> Delete key forums.opensuse.org/showthread.php/….

    I've modified the emoji annotation shortcut as suggested here, and it seems to work in e.g. gedit and LibreOffice Writer, but for some reason the emoji annotation is still activated by Ctrl+Shift+e in Visual Studio Code. Does anyone know why?

    @LiamBaker I have the same issue, have you found any solution? Commented Apr 30, 2020 at 3:59

    From my research, it seemed to be because I'm using the snap version of VSCode, which may include an old version of GTK which still has this behaviour (the 'feature' was removed in GTK 3.24, I believe). Apparently it is fixed if one installs the apt/deb version instead, although I haven't tried this yet; let me know if that works for you!

  • @LiamBaker Since ctrl+shift+e usecase in vscode is to open explorer, my solution was to change the combo to ctrl+e. (or alternative is ctrl+p): ``` { "key": "ctrl+e", "command": "workbench.view.explorer" }, { "key": "ctrl+shift+e", "command": "-workbench.view.explorer" }, { "key": "ctrl+shift+e", "command": "-workbench.action.quickOpenNavigatePreviousInFilePicker", "when": "inFilesPicker && inQuickOpen" } ```

Based on other answers here, I discovered that this keyboard shortcut defaults to Ctrl+. for anyone running Ubuntu with the KDE desktop environment.

Typing this shortcut displays the same "underlined e" character in a text box and doesn't seem to want to disappear unless I type some additional characters after it and hit Enter. Then it just leaves me with the additional characters I typed.

the "underlined e" character displayed after pressing this shortcut

using the ibus-setup command, I was able to confirm that, on my system, this emoji entry shortcut was set to <Control>period which I found myself accidentally hitting occasionally. Changing it to Ctrl + Shift + e will likely make this a lot less likely for me to accidentally activate
