Ctrl + R
Motivation: Copying the result of your calculation eliminates the need to manually write it down or memorize it. This makes it easier to use the calculated value in subsequent calculations or share it with others.
Example Output: After pressing Ctrl + R, the result of the most recent calculation will be copied to your clipboard.
Open the Formula Book
SpeedCrunch provides a formula book containing a wide range of predefined mathematical formulas and functions. To open the formula book, use the keyboard shortcut Ctrl + 1.
Ctrl + 1
Motivation: The formula book in SpeedCrunch acts as a reference guide, providing quick access to various mathematical formulas and functions. Opening the formula book allows you to easily retrieve the information you need for your calculations without having to search for it elsewhere.
Example Output: After pressing Ctrl + 1, the SpeedCrunch window will display the formula book, showing a comprehensive list of mathematical formulas and functions.
Clear the Calculator of Recent Calculations
To clear the calculator of recent calculations in SpeedCrunch, use the keyboard shortcut Ctrl + N. This will remove all the previous calculations from the calculator’s history, providing a clean slate to start fresh.
Ctrl + N
Motivation: Clearing the calculator of recent calculations allows you to have a clean working environment. If you’ve made a mistake in your calculations or want to start a new calculation from scratch, clearing the calculator helps avoid any potential confusion or errors.
Example Output: After pressing Ctrl + N, the calculator in SpeedCrunch will be cleared of any previous calculations.
Wrap Highlighted in Parentheses
SpeedCrunch allows you to wrap highlighted text in parentheses using the keyboard shortcut Ctrl + P. By default, if no text is selected, it wraps the entire expression.
Ctrl + P
Motivation: Wrapping highlighted expressions in parentheses can help ensure correct mathematical order of operations, especially when dealing with complex expressions. This keyboard shortcut provides a quick and convenient way to add parentheses to your calculations without needing to manually type them.
Example Output: After pressing Ctrl + P, the selected expression or the whole expression, if no selection exists, will be wrapped in parentheses.
Load a SpeedCrunch Session
To load a previously saved SpeedCrunch session, use the keyboard shortcut Ctrl + L. This will open a file browser dialog, allowing you to select the session file you want to load.
Ctrl + L
Motivation: SpeedCrunch sessions store your calculations and variables, allowing you to save your work and resume it later. Loading a session eliminates the need to reenter complex calculations or redefine variables, saving you time and effort.
Example Output: After pressing Ctrl + L, a file browser dialog will open, enabling you to choose the SpeedCrunch session file you wish to load.
Save a SpeedCrunch Session
To save your current SpeedCrunch session, use the keyboard shortcut Ctrl + S. This will open a file browser dialog, allowing you to specify the location and name of the session file to be saved.
Ctrl + S
Motivation: Saving your SpeedCrunch session enables you to preserve your calculations, variables, and formula definitions for future reference. By saving your session, you can easily return to it later without worrying about losing your work.
Example Output: After pressing Ctrl + S, a file browser dialog will open, enabling you to choose the location and name for the SpeedCrunch session file to be saved.
Toggle Keypad
SpeedCrunch provides a keypad interface that you can toggle on or off. To toggle the keypad, use the keyboard shortcut Ctrl + K. This is especially useful if you prefer using a mouse or touchpad instead of typing mathematical expressions directly.
Ctrl + K
Motivation: The keypad interface in SpeedCrunch offers an alternative input method for those who find it more intuitive or convenient compared to typing expressions manually. Toggling the keypad on or off based on your preferences allows for a customized user experience.
Example Output: After pressing Ctrl + K, the keypad interface in SpeedCrunch will be toggled on or off, depending on its previous state.
