Dezes is an advanced, high-performance TUI (Terminal User Interface) Win32 PE Disassembler and Hex Editor built in Rust.
It is designed for reverse engineers and binary analysts to disassemble x86/x64 executables, edit binary structures, and inspect program data efficiently.
-
π PE Binary Disassembler & Analyzer

coloured block edge
F2 Enter edit mode at cursor
Tab Switch edit column: HEX -> enc1 -> enc2
Shift + arrows Select a block in the focused column
Ctrl+C Copy that block (hex from the byte column,
decoded text from an encoding column)
Ctrl+E Edit Data dialog
~ Toggle upper/lower case of byte under cursor
Shift+V Paste hex or text bytes from clipboard

Shift + arrows Select a block in the focused column
Ctrl+C Copy that block
Ctrl+E Edit Data dialog (also works here)
~ Toggle case and advance
Esc / Enter Leave edit mode
Shift + movement Start / extend a selection (as in Disasm view)
Esc Clear the selection
Insert Fill selection with 0x00 (no selection: 1 byte)
Delete Fill selection with 0x90 NOPs (or just 1 byte)
~ Toggle case of the selection (or 1 byte)
Ctrl+C Copy the selection to the clipboard. What is
copied follows the column the block was
selected in: hex bytes, or the text those
bytes spell in enc1 / enc2
Ctrl+Z Revert changed bytes in the selection
Ctrl+K Modify Block dialog
Alt+M Colorize block (new or existing)
Mouse drag Selects too; Enter keeps the block, Esc clears it
Ctrl+B Open Find Pattern dialog (text or hex, Tab/Up/Down
to switch field, Enter searches the focused one)

:set Show every option and its current value
:set byteline <n|auto> Bytes shown per line (alias: width)
:set ctrlchar <c> Non-graphic byte placeholder character
:set enc1 <name> Primary encoding (utf-8, cp949, cp936,
iso-8859-1, iso-8859-2, utf-16le, utf-16be)
:set enc2 <name|none> Secondary encoding, same names plus 'none'
:set lang en|ko|zh Interface language (English, νκ΅μ΄, δΈζ).
Labels only: key names, option names and the
status-bar modes stay as they are
:set theme <name> Load a hex-view color theme. Disassembly
colors are left alone unless the theme file
declares them; use ':set disasmtheme' for those
:set disasmtheme <name> Disassembly colors only: dark, light, grey,
another theme name, or a path to a file
:set addr va|offset|toggle Address column contents
(':set va' and ':set offset' still work)
:set bitness <16|32|64|auto> Force the disassembly decoding width
:set view hex|disasm|text|header Switch view
Every on/off option below takes 'on', 'off' or 'toggle'; with no
value it turns on. The old 'no<name>' spellings still work.
:set highlight Disassembly syntax colors (alias: hilight)
:set hintbar Bottom hint line (hold Ctrl or Alt while it
is showing to see those bindings)
:set wrapscan Wrap search around EOF
:set db Write the .dzdb annotation sidecar file
:set dimctrl Dim control bytes
:set dimzero Dim null bytes (independent of dimctrl)
:set disasm_mem/reg/imm/kw/seg/import/import_fg/comment <color>
Disassembly colors, #rrggbb or a name
