Do you mean the icon with the mouse cursor and the question mark, which is called Enable Help Pointer?
If so, it will be hard to get back to the toolbar, because the developers of UE have forgotten to add it to the list of help commands at the customize dialog of V9+ style toolbars. (In the old style toolbar settings dialog, it is available.)
Write a bug report to IDM, that "Enable Help Pointer" is missing in the toolbar customize dialog.
To get it now back, you have to hack some binary settings in the registry. So be very carefully, if you follow my directives.
--------------
Close all UltraEdit instances, if any is open.
Open the registry with regedit.exe.
Open tree to HKEY_CURRENT_USER\Software\IDM Computer Solutions\UltraEdit\Toolbars State.
Export this key only with all it sub settings to a *.reg file, so you can restore the settings with double click on the REG file, if something is totally wrong after the modifications.
Double click at the right side on the binary setting named Toolbar_ID_?????. The five ????? are representing an individual number.
Set the cursor inside the binary values to the end after the last value.
Add now the 4 values 45 E1 00 00.
Press OK to save it.
Double click on the binary setting named Toolbar_ID_?????_ButtonsSettings to open it for modifying.
Increment the first byte in hexadecimal by a value of 1. The first byte is the button counter. Because modifying of a binary value is not possible, insert the new value of the button counter and delete the old one with the DEL key.
Now set the cursor inside the binary values to the end after the last value.
Add the 14 values 45 E1 00 00 1B 00 00 00 10 00 00 00 00 00.
Press OK to save it.
Double click on Toolbar_ID_?????_ButtonsSettings_Size.
Increment the value by hexdecimal 0E or 14 decimal.
Press OK to save it.
