hexedit

Two-pane binary editor for files on mounted storage. Each row shows a file offset, hexadecimal bytes, and their synchronized printable ASCII view. The number of bytes per row adapts to the terminal width. It uses the same 256 KiB PSRAM and 32 KiB internal-memory limits as edit.

Usage:

hexedit <file>

Controls:

• Tab switches input focus between the HEX and ASCII panes. The corresponding

byte remains highlighted in both panes.

• Hexadecimal digits replace the active high or low nibble in the HEX pane.

Printable characters replace the active byte in the ASCII pane.

• Arrows, Page Up/Page Down, Home/End, and Ctrl+Home/Ctrl+End navigate by byte,

row, page, or file.

• Shift with navigation extends a byte selection. Ctrl+A, Ctrl+C,

Ctrl+X, and Ctrl+V select all, copy, cut, and paste binary data.

• Backspace and Delete remove bytes. Typing at end of file appends data.
• Ctrl+S saves in place. Esc saves if needed and exits; the app-exit key

exits without forcing a save.

• Ctrl++ and Ctrl+- adjust editor text size for the active session.
