Make `ForwardChar` configurable to accept whole suggestion or the next word of it

Loving new the suggested line - just on quite small problem, and I half expect the answer to be “We know, we’re working on it”, but I couldn’t see it in the open issues.

Environment

PS version: 7.0.1
PSReadline version: 2.1.0-beta2
os: 10.0.18362.1 (WinBuild.160101.0800)
PS file version: 7.0.1.0
HostName: ConsoleHost (Windows Terminal)
BufferWidth: 172
BufferHeight: 39

I don’t think this is version dependent - apart from needing this version of PSReadLine,

Steps to reproduce

1. Start Powershell (7) and allow PSRL 2.1.0 beta 2 to load normally, then run Set-PSReadLineOption -PredictionSource History

2. Start typing a line from the history and see that it is suggested. Press right arrow to accept the line and then us left and right to move forwards and backwards along the line. Run or escape from the command.

3. Run Get-PSReadLineKeyHandler | where function -Match "accept" AcceptSuggestion and AcceptNextSuggestionWord are not listed

4. run Get-PSReadLineKeyHandler | where key -Match "rightarrow" only the normal cursor movements are listed.

5. I would like right arrow to be accept next word and ctrl+rightarrow or end to be accept all so I run

set-PSReadLineKeyHandler -Function AcceptNextSuggestionWord -Chord RightArrow
set-PSReadLineKeyHandler -Function AcceptSuggestion -Chord ctrl+RightArrow

1. Run Get-PSReadLineKeyHandler | where Key -Match "rightarrow" again these keys have lost their normal behavior

2. Verify that accept suggestion by work or whole line works, select left works, but select right doesn’t

Expected behavior

A key can work inside and outside “suggestion” mode (as with the default right arrow.).

Actual behavior

It can’t

Excellent , thank you.
Accept next suggestion word functionality does not seem to be linked to ForwardWord, so I have gone back to the default of right arrow accepting the line, with a version of your example to make ctrl+right work

Also, the ask can be easily satisfied by implementing a custom script block key binding, such as the one below.

Thank you 🙏, your code snippet script block helped me a lot, I used it like this:

# Accept the current inline suggestion
Set-PSReadLineKeyHandler -Key End -ScriptBlock {
       param($key, $arg)

       $line = $null
       $cursor = $null
       [Microsoft.PowerShell.PSConsoleReadLine]::GetBufferState([ref]$line, [ref]$cursor)

       if ($cursor -lt $line.Length) {
           [Microsoft.PowerShell.PSConsoleReadLine]::EndOfLine($key, $arg)
       } else {
           [Microsoft.PowerShell.PSConsoleReadLine]::AcceptSuggestion($key, $arg)
       }
}
