Summary

The key combination "Ctrl+j" in VSCode powerShell terminal failed to be assigned as PSReadLineKeyHandler

1. I've removed all of the "Ctrl+j" in the VSCode Keyboard Shortcuts menu.
2. My VSCode terminal using vscode-powerShell v2024.2.2 has the "Ctrl+j" being set as "AcceptLine".

However, this "Ctrl+j" key combination has no effect in the VSCode terminal using PowerShell.
In contrast, while working on the "ipython" opened in this vscode-powershell, the "Ctrl+j" works perfectly, but it doesn't work in vscode-powershell itself.

Moreover, the plain powershell window or powershell inside "Windows Terminal" are all working well while pressing "Ctrl+j" which stands for the AcceptLine in my setting.

Furthermore, the same methodology works well on any other key combinations.
The following figure use the "Ctrl+g" as an example.

Steps to Reproduce

1. Open powershell inside the VSCode
2. Set "Ctrl+j" as any function. (I want to set it as function AcceptLine)
   set-PSReadLineKeyHandler -Key "Ctrl+j" -function AcceptLine
3. Press the key combination "Ctrl+j" in the vscode-powershell window, and you would see nothing happening.

Start by reproducing the issue in the VS Code PowerShell terminal with set-PSReadLineKeyHandler -Key "Ctrl+j" -function AcceptLine, then compare it with Ctrl+g and standalone PowerShell behavior. Review the extension's keyboard handling alongside docs/troubleshooting.md; done means Ctrl+j invokes the configured PSReadLine handler in the integrated terminal.
