Settings, accessibility, and keyboard shortcuts

Settings apply to the desktop application, not just the current project. Project-specific search choices are stored with the project.

Appearance and numbers

Theme can follow the operating system or use Light or Dark mode. Accent choices are Indigo, Ocean, Emerald, and Amber. Ordinary status cues combine text or shape with color so meaning is not color-only.

Number format can be Automatic, Decimal, or Scientific. Significant digits are configurable from 2 through 15. Formatting changes how values are displayed; it does not reduce the precision used by search or stored results.

The selected interface language can follow the system or use any of the 30 bundled translations. A change that alters the effective language restarts the application after preserving recoverable work. Scientific formula and chart direction remains left-to-right in right-to-left interfaces.

Performance and storage

CPU workers: one through the processors available to Equarith. This preference sizes shared background calculations after the next restart; desktop symbolic search always uses every processor exposed to the application. Use the headless CLI --threads option to bound search parallelism.
Chart point budget: 10,000 through 2,000,000. A larger budget shows more interactive points but uses more preparation time and memory.
Autosave interval: 0 through 120 minutes. Zero disables scheduled autosave.
Recent-project count: 0 through 50.
Remember last-used directories: controls whether file choosers reopen in recent locations.
Automatically send encrypted anonymous error reports: enabled by default and immediately persisted when changed. The report allowlist and encryption details are documented in Licensing, privacy, and network access.

Settings also provides Check for updates, Open application data, Open log folder, View application log, and Reset all settings actions.

Reset restores application preferences, including re-enabling automatic error reports. It is not a project undo operation and should not be used to repair a damaged .equarith archive.

Accessibility

Equarith provides:

keyboard access to primary workspaces and common file/search actions;
visible focus indicators;
accessible names, summaries, and tooltips for controls and charts;
status text that does not rely on color alone;
reduced-motion behavior following the platform preference where available;
light, dark, and high-contrast-aware design tokens; and
right-to-left layout for Arabic, Hebrew, and Persian while preserving scientific left-to-right content.

Canvas-backed data and chart views avoid creating a UI node for every cell or point. Screen-reader summaries convey bounded high-level information; use exported CSV when every individual value must be inspected with another accessibility tool.

Global keyboard shortcuts

Use Command on macOS and Control on Windows or Linux.

Command/Control+N: new project.
Command/Control+O: open project.
Command/Control+S: save.
Command/Control+Shift+S: save as.
Command/Control+I: import data.
Command/Control+Q: quit.
Command/Control+Z: undo.
Command/Control+Shift+Z: redo.
Command/Control+C, V, A: copy, paste, and select all in the active context.
F5: start search.
Shift+F5: stop search.
Command/Control+1 through 6: open the six primary workspaces.
Command/Control+0: reset the workspace layout.

The Help menu contains the in-application Keyboard Shortcuts reference and a link to public documentation.

Data-grid keyboard use

Arrow keys move the active cell.
Enter starts or confirms editing.
Escape cancels the active edit or dialog action where applicable.
Shift extends range selection.
Copy and paste use tab-separated cells, compatible with common spreadsheets.
Column-header and selection context menus expose rename and deletion actions.

Long tasks run in the background. Announcements and progress are coalesced so rapid search events do not continuously steal focus.
