Hey there, I totally get missing that Apple keyboard navigation convenience—let's get your ThinkPad set up to match it. Below are two reliable methods depending on whether you're using X11 or Wayland (most modern Linux desktops use Wayland these days, like the default GNOME setup on the X1 Yoga).

Method 1: For X11 Environments (e.g., Xfce, older GNOME) #

We’ll use xmodmap to remap the key combinations directly:

1. Identify your keycodes
   Open a terminal and run xev. A small window will pop up—focus it, then press each Fn+arrow key pair one by one. Look for lines like keycode 113 (keysym 0xff50, Home) (your actual keycodes might differ). Jot down the keycode for each combination.

2. Create an xmodmap config file
   Open ~/.Xmodmap in your favorite text editor (e.g., nano ~/.Xmodmap) and add lines like this, replacing the placeholder keycodes with the ones you found:

   ! Map Fn+Left to Home
   keycode 113 = Home NoSymbol Home
   ! Map Fn+Right to End
   keycode 114 = End NoSymbol End
   ! Map Fn+Up to Page Up
   keycode 111 = Prior NoSymbol Prior
   ! Map Fn+Down to Page Down
   keycode 116 = Next NoSymbol Next
   

   The NoSymbol entry handles modifier combinations, and repeating the target key ensures the mapping works with Shift (e.g., Shift+Fn+Left selects text to the start of the line).

3. Apply and persist the mapping
   Run xmodmap ~/.Xmodmap in the terminal to test it immediately. If it works, set it to run on startup:

   • Add xmodmap ~/.Xmodmap to your desktop environment’s startup applications list.
   • If you use startx, add that line to ~/.xinitrc.

Method 2: For Wayland Environments (e.g., Modern GNOME) #

Wayland doesn’t support xmodmap, so we’ll use ydotool (to simulate key presses) and sxhkd (to listen for key combinations) as a flexible workaround:

1. Install required tools
   Open a terminal and install them with your package manager:

   # Debian/Ubuntu-based systems
   sudo apt install sxhkd ydotool
   
   # Fedora/RHEL-based systems
   sudo dnf install sxhkd ydotool
   
   # Arch-based systems
   sudo pacman -S sxhkd ydotool
   

2. Create the sxhkd config
   First, create the config directory if it doesn’t exist, then open the config file:

   mkdir -p ~/.config/sxhkd
   nano ~/.config/sxhkd/sxhkdrc
   

   Add these lines (use wev—Wayland’s event viewer—to find your Fn key’s actual name if XF86LaunchA doesn’t work):

   # Fn+Left → Home
   XF86LaunchA + Left
       ydotool key Home
   
   # Fn+Right → End
   XF86LaunchA + Right
       ydotool key End
   
   # Fn+Up → Page Up
   XF86LaunchA + Up
       ydotool key Page_Up
   
   # Fn+Down → Page Down
   XF86LaunchA + Down
       ydotool key Page_Down
   

3. Start sxhkd on boot
   Create a systemd user service to run sxhkd automatically:

   nano ~/.config/systemd/user/sxhkd.service
   

   Paste this content:

   [Unit]
   Description=Simple X hotkey daemon
   After=graphical-session.target
   
   [Service]
   ExecStart=/usr/bin/sxhkd
   Restart=always
   
   [Install]
   WantedBy=graphical-session.target
   

   Enable and start the service:

   systemctl --user enable sxhkd.service
   systemctl --user start sxhkd.service
   

Quick Test #

After setting up either method, open a text editor (like Gedit or VS Code) and try pressing Fn+Left/Right/Up/Down—you should jump to the start/end of the line, or scroll up/down pages just like your old Apple keyboard.
