Terminal key combinations not working properly

[gerane]

• VSCode Version: 1.2.0-insiders
• OS Version: Windows 10

Steps to Reproduce:

1. Open terminal using sysnative Powershell as default
2. Press key combinations like the following and it inputs the key mapping instead:
   • ctrl + c produces ^C
   • ctrl + left produces 5D
   • ctrl + right produces 5C
3. Using Shift combinations does not highlight text
   • shift + end Skips to end without highlight
   • shift + home Skips to beginning without highlight
   • shift + left moves left without highlight
   • shift + right moves right without highlight

So the regular Powershell terminal supports selection using those keybindings? Interesting that ctrl+arrow doesn't skip the word, that works fine on bash.

[gerane]

Yeah it works in regular powershell terminal, and it also works if you launch powershell from a cmd.exe prompt.

Here is an example of what it looks like inside of Code.

The only way to clear the line is to delete every character. There is also no way to copy text in the history or in the prompt. Pasting text is also very difficult.

These keys may be a limitation of winpty, or at least the quite old version that is being used.

Copying and pasting hasn't been looked at yet, the experience is terrible on all platforms. See #6451 #6945

ctrl + c , here copy selected area (missing in vscode terminal), insted it produces ^C

it's my elementary os terminal with this feature

ctrl + v, here paste whatever is in clipboard (missing in vscode terminal), insted it produces ^V

also it warn me if copy some command from web and what ti paste here with ctrl + v

ctrl + backspace in powershell is also not working. It only removes one character, while in native powershell and powershell launched through native cmd it removes the whole previous word.

Edit: Nevermind, it appears that ctrl + backspace doesn't delete the whole word on 32 bit powershell, which is what I was running in VSCode.

[elirnm]

In the latest insider's release ctrl + left/right no longer produce '5D/5C', but only move one character at a time rather than whole words. ctrl + c produces nothing rather than '^c'.

Thanks @AAurelianus, it looks like the adoption of xterm.js has improved the powershell situation 🎆

Here is the open issue for ctrl+arrow xtermjs/xterm.js#65 (it happens on Linux/bash too).

[elirnm]

@Tyriar actually my previous comment on ctrl + backspace does apply. In native powershell the sequence deletes whole words, in powershell in the integrated terminal it only deletes single characters, the same as unmodified backspace. This is both on 1.2.0 and the 2016-6-10 Insider release.

@gerane, I think the functionality for those keys is driven by PSReadline, not the terminal itself.

The terminal does seem to load PSReadline okay (the color highlighting works, no errors get thrown) but some of the functionality is lost. This might be due to the implementation of PSReadline?

[codymullins]

is this already being worked on or is it something I could create a PR for?

[Tyriar]

@codymullins not being worked on right now, I'm guessing its a problem within the https://github.com/sourcelair/xterm.js code base though (or the oldish https://github.com/rprichard/winpty version it uses when hooked up with pty.js).

Using vscode with windows native command line also the same problem with ctrl key

[Tyriar]

@Thaina ctrl+left/right in cmd.exe should work fine in the current insiders https://code.visualstudio.com/insiders

[idoo]

Is it possible to build CMD+K to clear current render in terminal?

[Tyriar]

@idoo a command to clear its being added in v1.6,the key binding will come a little later though #12585

[Tyriar]

Closing this off in favor of #11314 (blocking upstream issue: xtermjs/xterm.js#487)
