Keyboard Shortcuts

Complete keyboard shortcut reference for the Apple //e Emulator.


Table of Contents


Apple IIe Key Mapping

The emulator translates modern keyboard input to Apple IIe key codes. Standard alphanumeric keys and symbols map directly.

Your Keyboard Apple //e Key Notes
Enter Return Confirm input, run commands
Backspace Delete (left arrow) Delete character to the left
Escape ESC Cancel, exit menus
Tab Tab Tab character
Arrow keys Arrow keys Cursor movement, game controls
Space Space Space character

Special Keys

Your Keyboard Apple //e Key Notes
Left Alt Open Apple Modifier key, joystick button 0
Right Alt / Windows key Closed Apple (Solid Apple) Modifier key, joystick button 1
Ctrl Control Control key modifier
Shift Shift Shift modifier
Caps Lock Caps Lock Tracked and sent to the emulator core

Apple II Control Key Combinations

These are Apple IIe keyboard combinations, processed by the emulated machine, not the browser:

Combination Function
Ctrl+C Break -- stop a running BASIC program
Ctrl+S Pause screen output (Ctrl+Q to resume)
Ctrl+Q Resume output after Ctrl+S pause
Ctrl+G Bell (beep sound)
Ctrl+Reset Warm reset -- preserves memory, returns to BASIC or monitor
Ctrl+Open Apple+Reset Cold reset on real hardware (use the Reboot button instead)

Emulator Shortcuts

These shortcuts are handled by the emulator's JavaScript layer, not the Apple IIe:

Shortcut Action
F1 Open / close the Help & Documentation window
Ctrl+Escape Exit full-page mode and return to the normal view
Ctrl+V Paste clipboard text into the emulator at accelerated speed
Ctrl+` Open the Window Switcher overlay
Option+Tab Cycle focus to the next open window
Option+Shift+Tab Cycle focus to the previous open window

The arrow keys can additionally drive the joystick -- see the Cursor Keys toggle in Input-Devices. They keep working as keys while it is on.

Debugger Shortcuts

These shortcuts control the CPU Debugger when the emulator is paused at a breakpoint or in single-step mode:

Shortcut Action Description
F5 Run / Continue Resume execution until the next breakpoint
F10 Step Over Execute one instruction, stepping over JSR subroutine calls
F11 Step Into Execute a single instruction, following into subroutines
Shift+F11 Step Out Continue execution until the current subroutine returns (RTS/RTI)

These shortcuts work globally -- you do not need to have the CPU Debugger window focused.

Window Management

Shortcut Action
Ctrl+` Open the Window Switcher (shows all available windows organised by category)
Option+Tab Cycle to the next visible window and bring it to focus
Option+Shift+Tab Cycle to the previous visible window

The Window Switcher displays windows in five categories:

  • System -- Screen, Disk Drives, Save States
  • Hardware -- Display Settings, Joystick, Expansion Slots, Mockingboard, Mouse Card
  • Debug -- CPU Debugger, Rule Builder, Soft Switches, Memory Browser, Memory Heat Map, Memory Map, Stack Viewer, Zero Page Watch
  • Dev -- Applesoft BASIC, Assembler
  • Help -- Documentation, Release Notes

Click a window name in the switcher or use Tab cycling to navigate between open windows.

Assembler Editor

These shortcuts are active when editing assembly source in the Assembler Editor window.

File Operations

Shortcut Action
Ctrl+N (Cmd+N) New file
Ctrl+O (Cmd+O) Open file
Ctrl+S (Cmd+S) Save file

Editing

Shortcut Action
Ctrl+Enter (Cmd+Enter) Assemble the current source
Ctrl+/ (Cmd+/) Toggle comment on the current line
Ctrl+D (Cmd+D) Duplicate the current line
Tab Move cursor to the next column (label / opcode / operand / comment)
Shift+Tab Move cursor to the previous column
Enter Smart indent (auto-aligns to the appropriate column on new line)

Breakpoints and Panels

Shortcut Action
F9 Toggle breakpoint on the current line
F2 Toggle the ROM reference panel

Mouse Capture

Shortcut Action
Alt+Click on screen Engage pointer lock for Apple Mouse Card input
Escape Release pointer lock (standard browser behavior)

Mouse capture requires the Apple Mouse Card to be installed in an expansion slot. See Expansion-Slots for card configuration.

Text Selection and Copy

Action How
Select text Click and drag on the emulator screen
Copy selected text Ctrl+C (Cmd+C on Mac) while text is selected
Paste text Ctrl+V (Cmd+V on Mac) when the screen has focus

Text selection works in both 40-column and 80-column text modes. The selection overlay appears directly on the canvas.

Notes

  • Browser shortcuts are preserved -- Ctrl+R (reload), Ctrl+T (new tab), and other standard browser shortcuts are not intercepted by the emulator and work normally.
  • Focus matters -- Keyboard input is only sent to the Apple IIe when the emulator screen canvas has focus. Click the screen to focus it. If a debug window or text input field is focused, keys go to that element instead.
  • Mobile devices -- On touch devices, tapping the screen opens the on-screen keyboard via a hidden input element.
  • Key codes are sent raw -- The JavaScript layer sends raw key codes to the C++ core, which handles the full Apple IIe keyboard translation including modifier state.

For general usage see Getting-Started. For debugger details see Debugger.
