Sheets strip shows 1, 2, … In Sheets… you can delete the open sheet whenever at least two exist.
The app uses the same compact layout on phones and desktops: the page doesn’t scroll; only the gutter, notebook, and results columns scroll. Nested [expenses.housing] headers form a tree; sum([expenses]) walks that branch and expenses.housing.mortgage looks up a leaf. The draggable strip at the bottom is the operator keypad; Insert holds paths, sections, aggregates, duplicate, and undo.
expenses.housing.mortgage when that line assigns a name in a section, otherwise @ksum([expenses])ans is the same as @r1 (previous line)#, or put # … after an expression on the same line[income] or dotted [expenses.housing] — nesting is the path, not indentationsum([expenses]) walks every numeric leaf under that branch (including expenses.housing, expenses.transport, …). Same for avg, min, max, countexpenses.housing.mortgage — follow the tree to a named leafjob = 45000 — later job, income.job, or still @job. Letters like æ ø å are allowed in nameschildren([expenses]) lists direct child paths; names([expenses]) lists only the last segment= or a trailing operator, or starts with + * / ^[results]) so they are not counted as data= still work; reference them by gutter line: @5@r1 line above, ans same as @r1sum(@1:@3), avg(above(3))sin, cos, tan, sqrt, ln, log (base 10), exp, abs, round(x) or round(x, 2), coalesce(a, b, …) — trig uses radianspi, PI, π, tau, eline / line() — current gutter line index (numeric), e.g. line*10Ctrl+Z / Ctrl+Shift+Z or Ctrl+Y (Cmd on Mac)Alt+↑ / Alt+↓ — move current line up or down (Option on Mac; also Ctrl+Shift+↑/↓)One line per notebook row — same order as lines in the sheet. Blank and comment rows are empty lines. Numeric values use full precision without thousands separators (same as Menu decimals cap). Tap Copy column or select the box and copy.
