HexTex

The Hex Viewer/Editor in Textual

Keys

• Use Ctrl+w to change the display width of the units (1, 2, 4, or 8 bytes)
• Use Ctrl+l to toggle the display endianness of the units (little/big endian)
• Use Ctrl+g to go to an offset in the file
• Use e to edit the currently selected cell value
• Use Ctrl+s to save changes to the file

Features

• Multi-width Display: View data as bytes, words, dwords, or qwords
• Endianness Toggle: Switch between little-endian and big-endian representations
• Hex Editing: Edit cell values directly with hex input validation
• Synchronized Views: Hex and ASCII views stay in sync as you navigate
• Modified Indicator: Status bar shows when file has unsaved changes
• Safe Editing: Modal dialog with input validation prevents invalid hex values

Issues

• On occasion, the synchronization between the two data tables will cause a fast flickering between two locations as the highlight updates between two coordinates. Sometimes this can be resolved by using the Ctrl+g to go to a specific offset, like 0.
