Word-jumping&deleting does not work on Windows

[BennyFaaren]

Hello,

I cant jump words with ctrl+arrow key and deleting a word with ctrl+backspace does not work either, beside it is configurated as hotkey.

Copy and Paste with ctrl does work.

Windows 10 and latest version of Terminus.

So far I can only report it works with windows 10 (Microsoft Windows [Version 10.0.18363.900]) and App-version 1.0.112 using a SSH connection.

Which shells are you using?

Which shells are you using?

Specifically - Local Powershell (core and local):

PS C:\Users\cavejay> $PSVersionTable

When using CTRL+left CTRL+right in Powershell Core 'b' and 'f' get printed respectively. In normal powershell nothing is printed.

I have the same problem. In cmd ctrl+backslash prints ^H and in powershell nothing happens.

Only using git bash does work as expected, all other shells print a/f/h or nothing

[cavejay]

Found some time to poke around this issue:

• Alt+Arrow Keys work in the way CTRL+Arrow Keys are expected to work
• Terminus uses the same node library (node-tty although Eugeny did fork it) under the hood as Microsoft's 'Terminal' app.
• Terminal has a working CTRL+Arrows and CTRL+Backspace/Del function but also prints ^H when using Alt+ ** Terminal's escape codes look similar to Terminus's, with Backspace + Alt's code matching Terminus' delete-previous-word. This is likely why both of these key combos only print ^H.

I've built Terminus to use the \x8 code used by Terminal for Backspace + CTRL and didn't seem to have any success and am at the limit of my knowledge for how tty's etc function. This problem is irritating me so I'll likely find more time in future to explore.

@Eugeny would you have an off the cuff guess at what the cause of this is that I could use to look further?

[Eugeny]

@cavejay thanks for the investigation! I've managed to dig up the escape sequences for Ctrl-Left, Ctrl-Right and Ctrl-Delete, but it doesn't looks like there's anything else besides ^H for Ctrl-Backspace and PowerShell doesn't accept it over ConPTY.

Describe the bug The backspace key not working

Information about your version 1.0.205

Additional context While accessing Nokia/Huawei OLT through telnet, the backspace key doesn't function and you have to use the Ctrl+H key. Whereas the SSH connection to switches and routers the backspace key works fine.
