How to get the most out of DeskCalc

Calculator modes, export workflows, keyboard shortcuts, system setup — everything you need to master the tape calculator.

Section 1

Calculator modes

Classic 10-key tape workflow — type values, see them stack on the running paper tape.

Type full expressions like 2 + 3 * 4 and get instant results.

Use DeskCalc as a drop-in replacement for the Windows calculator — same keys, more features.

Section 2

M+, M−, MR, MC functions with the active memory value always visible in the header.

Position counter, simultaneous tapes, load / save, editable entries — your number history, your way.

Built-in currency conversion with up-to-date rates — convert any tape value with a single click.

Spoken numbers and operators for audit-style proofreading — listen to your entries as you key them in.

One-click capture of numbers from any window — invoices, browser pages, PDFs — straight onto the tape.

All shortcuts at a glance — fly through calculations without ever touching the mouse.

The full feature reference — every option, every flag, every keyboard combination in one place.
