How Are Special Keys Shown in the Log?

Non-printable keys such as Enter, Backspace, the function keys and arrows appear in the log as short bracketed tags like [Ent], [Bck] and [F5].

Printable characters appear in the log as themselves. Special keys — the ones that don't produce a visible character — are written as short tags in square brackets.

Common tags

Tag	Key
`[Ent]`	Enter
`[Bck]`	Backspace
`[Tab]`	Tab
`[Esc]`	Escape
`[Del]`	Delete
`[Ctl]`	Control
`[Alt]`	Alt
`[Win]`	Windows key
`[Cap]`	Caps Lock
`[Ins]`	Insert
`[Hom]` / `[End]`	Home / End
`[PUp]` / `[PDn]`	Page Up / Page Down

`[F1]` … `[F12]`	Function keys
`[Prn]`	Print Screen
`[Num]` `[Scr]`	Num Lock / Scroll Lock

Numeric keypad

Keys on the number pad carry an N suffix — for example [5N], [+N], [.N] (Delete on the keypad) and [/N]. Depending on Num Lock, these double as navigation keys.

Bottom line

If you see a bracketed code like [Ent] or [F5] in the log, it's simply a special key rendered as text so the whole session reads back cleanly.
