Línea de trabajo

Start by reproducing the F1 ShowCommandHelp cases described in the issue: content, item, and variables in PowerShell 7.4. Check how fuzzy command and about_* topic matches are collected and presented. Done means all relevant matches are found consistently, a single match opens directly, and multiple matches are presented so the user can select a topic.

Steps to reproduce

Even though it isn't currently documented, ShowCommandHelp also recognizes parts of conceptual about_* topic titles and partial command names.

However,

  • this recognition is inconsistent
  • sometimes, instead of displaying what is seemingly a single matching topic directly, it is presented in a list as if multiple topics had matched.
# OK: Shows list of matching command help topics: Add-Content, Clear-Content, ...
PS> content # <- press F1 here

# !! about_* topic seemingly SHADOWS command lookup: only about_PSItem is shown, not also Get-Item, ...
PS> item # <- press F1 here

# !! Even though *two* matching about_* topics exist - about_Automatic_Variables and about_Variables - 
# !! only *one* is shown (about_Automatic_Variables), and unexpectedly in a *list* instead of directly.
PS> variables # <- press F1 here
