- Help for !HexEdit
- =================
-
- This application allows you to view and edit any
- type of file byte by byte (by entering hexadecimal
- values or typing characters)
- The operations available are as follows:
-
-
- Once !HexEdit is running:
- =========================
-
- Double-click DATA files to load them Drag any file to
- iconbar icon to load it
-
- Click on any character or hexadecimal digit in the
- window to select it for editing-- Both the hexadecimal
- value of the byte and it's corresponding ASCII
- character equivalent are highlighted.
-
- Now, any character you type will overwrite the
- character that is currently selected, and the
- selection will move on to the next character.
-
- To enter hexadecimal digits instead of typing
- characters, press 'Insert'. The computer will beep to
- let you know the entry mode has changed. Now, type any
- hexadecimal digit-- The selected byte will be modified
- as follows: The righthand digit will move into the
- left, and the 'space' left on the righthand side will
- then be replaced by the digit you type.
-
- Press 'Insert' again to toggle back to character mode.
-
-
- From the main menu:
- ===================
-
- Use File ⇨ to get info on the file Use Save ⇨ TO SAVE
- the modified file
-
- Use GOTO ⇨ to go to a specific address
- (format: xxxx in HEX)
- or format: +xxxx (hex) to jump forward xxxx bytes
- -xxxx (hex to jump backwards xxxx bytes
-
- Use GOTO ⇨ 9999999 (large number) to go to end of file.
-
- Use Undo to undo the last change you made (undoes one
- byte at a time) {Please note that if you undo ALL the
- changed bytes, then HexEdit is clever enough to
- realise that the file has not in effect been changed,
- and so will not ask if you wish to save etc. when you
- close the window.}
-
- Type a search string into the 'Search' option, and
- HexEdit will search from the currently selected byte
- for that string. If a search is taking a while,
- HexEdit will display the Hourglass pointer, along with
- a percentage that represents how far it has searched
- between the selected byte and the end of the file
- (i.e. gives some indication of the maximum time left
- to go). If HexEdit reaches the end of the file without
- finding any occurrences of the string, it will beep.
-
- Shortcuts:
- ==========
-
- Movement:
- You can select any byte by clicking on it's
- hexadecimal value, or on it's ASCII equivalent.
-
- You can move the selection with the keyboard cursor
- keys.
- If you use shift in conjunction with ⇩ and ⇧, you
- will move up/down the data by 16 lines instead of one.
- This is duplicated by the page up/down keys.
- If you hold down CTRL with ⇩ or ⇧, you will be moved
- to the start or end of the file.
-
- Pressing RETURN or TAB will move you to the next
- byte.
-
- Pressing delete or backspace will UNDO the last byte
- you changed, up to a maximum of 100 bytes.
-
- Pressing 'COPY' will set a mark at the presently
- selected byte. This makes it easy to move back to this
- byte later.
-
- Pressing 'HOME' will move you to the next mark
- (cycling through the marks, so when the last mark is
- reached, you will move to the first one)
-
- Pressing f10 will swap the case (A ⇨ a, a ⇨ A, etc)
- of the character represented by the currently selected
- byte.
