TL;DR
A GNOME developer has submitted code to disable the traditional middle-click paste behavior in GNOME and has filed a related bug against Firefox. Supporters argue the feature is an X11-era quirk that causes accidental pastes; critics point out the shortcut uses a separate PRIMARY selection and has decades of Unix history.
What happened
GNOME developer Jordan Petridis opened a merge request to stop enabling middle-click paste by default in GNOME, describing the behavior as an "X11ism" and signaling a move away from it. He also filed Firefox bug 1747207 proposing the browser drop the same behavior, arguing it is little-known, not discoverable and often triggered accidentally. The Register’s opinion piece pushes back, noting that middle-click paste uses the PRIMARY selection rather than the clipboard and enables workflows where two separate selections can be pasted independently. The article traces the feature’s roots through Unix history, citing references in SunOS/IRAF documentation, early X-era usage and coverage of the behavior in Linux-era writing dating back to at least 2004. The story also touches on broader user-interface shifts in GNOME, including how client-side decorations have previously altered window-management features.
Why it matters
- The change would affect a long-established input behavior relied on by many Unix/Linux users.
- Middle-click paste uses a different selection mechanism (PRIMARY), enabling workflows that the clipboard alone does not support.
- If adopted systemwide or in major apps like Firefox, the removal could force users to change muscle-memory-driven workflows.
- The proposal has prompted discussion about discoverability, accidental activation, and broader UI design decisions in GNOME.
Key facts
- Jordan Petridis submitted a merge request to remove middle-click paste from GNOME defaults.
- Petridis filed Firefox bug 1747207 proposing the browser also stop supporting middle-click paste.
- He characterized the feature as an "X11ism" and noted concerns about accidental clicks and discoverability.
- The Register notes the middle-click pastes the PRIMARY selection, not the clipboard, allowing two-selection workflows.
- Historical references in the source point to usage in Unix systems (SunOS/IRAF) and early X-era tooling, with Linux-era mentions from at least 2004 and a Mozilla bug from 2005.
- The Register’s writer describes the feature as long-standing and valued by many users familiar with Unix heritage.
- The source notes GNOME’s move toward client-side decorations has already affected some window-management behaviors.
What to watch next
- Whether GNOME accepts and merges the proposed change into defaults — not confirmed in the source
- Whether Firefox responds to bug 1747207 by altering its middle-click paste behavior — not confirmed in the source
- Community reactions and any accessibility or workflow impact assessments from GNOME and other projects — not confirmed in the source
Quick glossary
- X11: A windowing system for bitmap displays common in Unix and Unix-like operating systems; often associated with long-standing input and display behaviors.
- PRIMARY selection: An X11-era selection mechanism that stores selected text and can be pasted with a middle-click, distinct from the clipboard.
- Clipboard: A system-provided storage area for copied or cut data that applications can paste using explicit commands like Ctrl+V.
- Client-side decorations: Window frames and title bars drawn by the application itself rather than the window manager, which can change how window controls and behaviors behave.
Reader FAQ
Has GNOME already removed middle-click paste?
A merge request to change the default was submitted, but whether it has been merged or applied is not confirmed in the source.
Is Firefox dropping middle-click paste?
A bug report proposing that change (1747207) was filed, but any decision or action by Firefox is not confirmed in the source.
Does middle-click paste use the same clipboard as Ctrl+V?
No. The source explains middle-click pastes the PRIMARY selection, which is separate from the clipboard.
Why do proponents want it removed?
According to the developer who filed the requests, the feature is little-known, not discoverable and can be triggered accidentally.
