Getting Started with SpeedCrunch Portable: A Quick Guide

SpeedCrunch Portable Tips & Shortcuts for Power Users

Quick setup

• Install: Extract the portable package to a dedicated folder (e.g., D:\Apps\SpeedCrunch) so settings stay with the app.
• Settings file: Back up the speedcrunch.ini (or equivalent) to preserve custom functions and shortcuts.

Interface shortcuts

• Calculate current line: Enter
• Evaluate expression without moving cursor: Ctrl+Enter
• Navigate history: Up / Down arrows
• Jump to matching bracket: Ctrl+M
• Select expression: Ctrl+L or double-click an expression

Editing & input tips

• Use function autocomplete: Start typing function names (sin, log, etc.) — SpeedCrunch autocompletes and shows argument hints.
• Insert constants quickly: Type constant names (pi, e) or use the constants sidebar if enabled.
• Multi-line calculations: Use Shift+Enter to add a newline without evaluating; useful for building step-by-step work.
• Copy result only: Right-click result → Copy Value (or use the result menu) to copy numeric output without formatting.

Custom functions & variables

• Create reusable functions: Define functions inline, e.g., f(x)=x^2+2*x+1 and save them in the settings file for reuse.
• Persist variables: Assign variables (a=5) in a session; export your variables by copying the definitions to the config file for future sessions.

Performance & portability

• Keep portable folder small: Remove or compress large logs/plugins to speed startup.
• Use on USB safely: Always close SpeedCrunch before ejecting the drive to avoid corrupted settings.

Advanced shortcuts & tricks

• Matrix entry: Use square brackets with semicolons for rows, e.g., [[1,2];[3,4]].
• Complex numbers: Enter using i, e.g., 2+3i, and use abs(), arg() for magnitude/angle.
• Precision control: Set number of decimals in Settings or use format(n, digits) for one-off control.
• Expression chaining: Use semicolons to run multiple expressions in order: a=2; b=3; a*b
• History export: Copy the history pane to retain session calculations externally.

Troubleshooting

• Reset to defaults: Rename or delete the ini file to reset settings.
• Plugin issues: Temporarily disable plugins by moving them out of the plugins folder.
