Try using Ctrl + Shift + Right, text should be selected at word boundaries. a terminal, then close it using command. using Ctrl + Shift + Right again. Expected: Text should be selected at word boundaries. Actual: No text is selected. Cursor doesn't move at all. This is the the same issue as filed at [1] and [2]. If it's reproducible in 3 server implementations (counting openvscode-server), then it's probably an upstream issue. Sadly I don't have an access to GitHub Codespaces, so I can't verify it with an "official" implementation [3]. You'll notice in keyboard troubleshooting log below the following 2 lines: It's been suggested in [1] that vscode might still think that is active despite the terminal is closed. Thus, a workaround I've been using is to have the following in (with default unbind): That is, wherever exists, augment it with . [3] I mean, doesn't have terminals. I've tried using Live Share; that doesn't change. See Keyboard shortcuts troubleshooting. The first keypress is before the terminal is opened. The other two are after it's closed.

I can't reproduce this issue in Firefox or Safari.
you mentioned Safari, which implied that you have macOS. Could you please re-try using Linux or Windows? macOS uses Command key for those keybindings, and so duplicated keybindings doesn't exist. Folks at cdr/code-server can't reproduce it on macOS either, but subsequently can reproduce it on Linux. Please re-open this issue.
doesn't reproduce for me there either !
That looks like Microsoft Edge, based on Chromium engine. Could you please try again on Firefox?
I can reproduce this in Ubuntu/Firefox
Does not repro on Ubuntu/Edge
Created a PR with a workaround
