Enter and Tab on a tag word tell an event reader as a click on it does, at its place in the tag; only a look takes a diff line's address, an exec there takes the word (follows vpmzwuzk)

One Look path: Enter, Tab and a bare Look take what a click at the cursor takes, a diff line's address included, and an event reader is told of them as of a click

2026-10-01T20:30:33Z

The keyboard expanded the cursor's word on its own (look.expandedSel), so a diff line's address (and a hunk line's code word, without its +/-) was the mouse's alone: Enter on `+line` looked for the text in the diff. Now exec.operandAt is the one expansion: pointerOperand is it with a gesture's selection borrowed, the Enter/Tab path and a bare Look (exec.currentOperand) are it from the cursor, and both dispatch through mouse.dispatchPointerBuiltin, so a pane with an event reader hears a key's look or exec as a click's. A test runs one diff line and one file:12:5: line through a B3 click, a B3 sweep, Enter, a bare Look, the look file and an event write-back, and asserts each lands in the same file, line and column.

Alt/Option-click is B2 and Super/Cmd-click is B3, sweeps included, as in plan9port: a one-button trackpad can execute and look

2026-10-01T15:58:23Z

The core decides it at the press (mouse.emulateButton) and keeps it to the release, whatever keys are let go between. Ctrl-click stays a definition, and a program tracking the mouse still gets the plain click (Alt as its meta, Super as nothing). The SDL, macOS and web shells now pass Super; the macOS and web shells pass Alt on a click too. A terminal's mouse report has no Super bit, so in a terminal only Alt-click is B2.

Over a program that tracks the mouse, B2 and B3 are pardes's execute and look, as in any pane, and Shift sends them to the program as its buttons 2 and 3; B1 and the wheel stay the program's, Shift keeping them pardes's

2026-10-01T03:12:17Z

The Shift that sends B2 or B3 is left out of their reports and of the drags they hold: it only chose the target. A B2 or B3 sweep of pardes's moves nothing to the program under 1003. Co-Authored-By: Claude Opus 5.5

A program that tracks the mouse gets its clicks, drags and moves over its grid, in the format it chose; Shift keeps pardes's select, execute and look, and chrome is never the program's

2026-10-01T03:12:17Z

Presses and releases under 1000, drags with a button down under 1002, every move once per cell under 1003, X10 presses under 9, in raw terminal input only. A press the program took keeps its drag and release, reported clamped to the grid's edge wherever the pointer goes. The press also makes the pane the active one. docs/tags.md says so.

A mouse event carries Shift and Alt as well as Ctrl, from SDL and from the tty's input; a program's wheel report carries them as xterm counts them, and Shift keeps the wheel pardes's own scroll

2026-10-01T03:12:17Z

The reports are ghostty's encoder now (shift+4, meta+8, ctrl+16), with the mode and format ghostty tracks. The detached wire carries the two new bits: version 9. The test shell's ESC]777;mouse takes an optional fifth field of modifiers. Co-Authored-By: Claude Opus 5.5

A wheel over a terminal whose program owns it goes to the program: its mouse report when it tracks the mouse, arrow keys on the alternate screen with alternate scroll, so codex, htop and less scroll

2026-10-01T03:12:17Z

codex 0.158 moved its chat onto the alternate screen with any-event SGR mouse tracking (1049, 1000/1002/1003/1006, 1007 off); its sign-in screen keeps 1007 on with tracking off. pardes never forwarded a wheel to a program, only scrolled ghostty's scrollback, which the alternate screen does not have, so the wheel did nothing there. A shell on the main screen still scrolls its scrollback as before. Co-Authored-By: Claude Opus 5.5

A middle or right sweep over a column's or the workspace's tag runs or looks for what it swept, as a pane tag's does

2026-10-01T03:12:17Z

Both headers acted on the press: a middle or right press ran, or looked for, the word under it (or the header's selection when it was on that) at once, so a drag had nothing left to do. A sweep of `echo SWEPT` in a column tag ran a bare `echo`. They have done so since the headers were drawn apart from the panes; it is no regression, and the -l/Restore allocator fix (ompukopz) does not touch it. Now a press on a header holds a HeaderSweep (the column by its serial, or the workspace), which the drag extends, held to the header's row and text as a pane tag's sweep is. It is painted in its button's tint meanwhile, and the release runs what it swept in that header's context; a release that has not moved runs the word or selection a click always did. The other of middle and right cancels it (acme 2-3/3-2); the select button is inert, as a header's command already takes the held selection as its argument. Running on the release, a builtin from a header is announced as one from a pane tag is: the press used to set the announcement and the release clear it at once. find, restore, theme, topbarexec, ttyhelp, tutor and windowops re-recorded for that badge alone. headersweep.snap sweeps the column and workspace tags with the middle button and a word part with the right one, and cancels a sweep; headersweep-restored.snap sweeps both after Dump and Restore.

Terminal.zig is terminal.zig: a file of functions and no fields takes a namespace's lowercase name

2026-10-01T03:12:17Z

The last of the deferred renames, now that the tty and theme agents have landed: panes.terminal at its importers, the alias lines in Text.zig and File.zig and panes.zig's own uses following. dump.zig's Terminal struct, a dump record, is not this. The served sources list and docs/design.typ name the new file. test/perf.zig's references change, so the three perf baselines take its new harness id with their numbers as recorded. No behaviour changes. Co-Authored-By: Claude Opus 5.5

tag_layer.zig folds into Layer.zig, whose TagHit its two functions work on

2026-10-01T03:12:17Z

Two functions (sameCell, columnAt) on Layer.TagHit, 32 lines with their imports, used by edit.zig, mouse.zig and look.zig: they sit with the type now, called Layer.sameCell and Layer.columnAt. docs/design.typ names Layer.zig in its place. No behaviour changes. Co-Authored-By: Claude Opus 5.5
