There are several methods to work on two different places of same file.
The first one is using Window - Split Window
which can be also achieved by left clicking on the small rectangle above the vertical scroll bar resulting in a change of the mouse pointer to a double line with an up and down arrow indicating that you now can move the dividing line displayed across the document window now up or down to split the document window into 2 panes. That's a common Windows feature which is supported also by MS Word, MS Excel, Adobe Reader, ... To get rid of the two panes of a document window, just move the dividing line to bottom or top of the document window and you get back a single pane window. Switching between the panes can be down by key using F6 or Shift+F6. (The keys can be changed in the key mapping configuration dialog - FocusNextPane, FocusPreviousPane.)
Next it is possible to duplicate a window by using Window - Duplicate Window
. Now you have two separate document windows of same file in same instance of UltraEdit which you can arrange like you want, see How to configure the appearance of the open file tabs bar in UE v15.00 and later?
where the document window management is also explained briefly.
Since UE v19.00 it is possible to drag a file tab outside of UltraEdit to open it in new instance of UltraEdit, i. e. move a document window with all its settings to a new instance of UE. For UltraEdit versions prior 19.00 first the new instance of UltraEdit must be started via the Advanced
menu before the document window of a file can be moved into this new instance of UE.
And of course you can start a new instance of UltraEdit and open there the same file as long as you have configured to open files with usage of a temporary file. The fastest method to open a file a second time in another instance (clone document window) is perhaps using Edit - Copy File Path/Name
, Advanced - Open New Instance of UltraEdit
, Ctrl+O (File - Open) or Ctrl+Q (File - Quick Open), Ctrl+V (to paste copied file name with full path) and RETURN to open the file in the new instance.
