Larry Tesler pioneered cut-and-paste, the one-button mouse, WYSIWYG (2005)

Original Article ↗ Hacker News Discussion ↗

Larry Tesler’s legacy as the “inventor of cut and paste” is re‑examined in light of his broader influence on user interfaces, including modeless interaction, the one‑button mouse, and early WYSIWYG editing. Commenters debate what it really means to “invent” concepts like cut/copy/paste or WYSIWYG, contrasting Tesler’s digital implementations and terminology with earlier physical and software precedents. The conversation expands into wider critiques of modern UI trends—such as increasingly inconsistent mobile and desktop interfaces and Amazon’s cluttered design—while highlighting Tesler’s lasting ideas like the Law of Conservation of Complexity and his indirect role in Apple’s survival through its ARM investment.

Reposting and Tesler’s Legacy

  • Several note this is an old article resurfacing; some see “inventor of cut/paste” as reductive.
  • Others argue that focusing on cut/paste is effective for lay audiences and conveys how early and influential his work was.
  • Some point out that he also helped coin or popularize terms like WYSIWYG, “browser,” and “user friendly,” and pushed modeless, user-centered design.

Cut/Copy/Paste: Invention vs. Adaptation

  • Multiple comments stress “cut and paste” existed as a physical publishing process long before computers.
  • Early editors (TECO, etc.) already had similar operations; Tesler is framed more as adapting and naming the concept for GUIs.
  • A key contribution highlighted is the selection model: cursor as “between characters,” selection as a range, and unified replace/insert behavior.
  • Some dislike that cut/paste introduces “hidden state” (clipboard) and prefer select-and-move or X11-style primary selection.

Modes and Interaction Philosophy

  • Tesler’s “no modes” principle is widely cited as influential; some see cut/paste as in tension with it.
  • Others note that modern tools (e.g., modal editors like Vim, car “eco/sport” modes) show modes can be powerful but must be used sparingly.

One-Button Mouse Debate

  • Strong disagreement: some call it one of the worst ideas, arguing at least two or three buttons are needed and double-click is undiscoverable and confusing.
  • Others defend it as the right choice for 1980s novices, reducing complexity vs. multi-button PARC mice with inconsistent semantics.
  • There is discussion of keyboard modifiers effectively giving the Mac “virtual” extra buttons.

WYSIWYG vs. Markup

  • Some argue WYSIWYG was revolutionary for its time, democratizing desktop publishing.
  • Others think it was a bad long-term idea: encourages ad‑hoc visual poking instead of structured document semantics, causing fragile layouts.
  • Alternatives mentioned: print preview, TeX/Markdown flows, “reveal codes,” and human-readable markup generated from visual tools.

Broader UX Themes

  • Multiple commenters lament modern regressions: inconsistent mobile UIs, loss of tooltips/manuals, touch paradigms leaking into desktop.
  • Amazon’s interface is criticized as cluttered and confusing; anecdotes suggest internal resistance to redesign, possibly for business reasons.

Other Contributions and Concepts

  • The ARM/Newton investment is noted as indirectly crucial to Apple’s survival.
  • Tesler’s Law (conservation of complexity) is referenced as a useful mental model: complexity can be shifted but not eliminated.
