GNU nano 8.5 “Sigourney” brings saved anchors, new keystrokes and improved syntax coloring

GNU nano 8.5, code-named “Sigourney”, delivers key editing improvements for command-line users. Anchor positions are now preserved between sessions if the --positionlog option is active, making it easier for those working with lengthy files to resume precisely where they left off. In addition, the editor now exits with an error status when users press either ^O^Q or ^X^Q, a small but valuable change that can help experienced users detect and handle unexpected exits within automation workflows.

Additionally, nano has modified its keyboard behavior: the ^L keystroke now centers the cursor, with the M-% command becoming the new way to cycle it. Syntax coloring also sees improvements, now working more reliably across a broader range of language locales.

Finally, the release includes an undocumented --whitespace option. The lack of accompanying information about its functionality is noted, piquing interest among advanced users willing to experiment with new or hidden features.
