Copy any lines to config called by "Settings-user" and edit lines in this '''user config'''. You can copy comments near options too, they will be ignored. Default config is not read by program, it's only to show options to user.
 
 '''Lexer-specific config''': settings which are read when some lexer activates. E.g., if you open Pascal file, config for Pascal is read after user config. You should not write "ui_" options to lexer-override config (it will give some weird effects on changing lexers), and few others, like option "lexlib" (it is read only once).

+(From version 1.7.0.3)
+To paste like in Linux, with middle-click, you need
+
+* set option "mouse_mid_click_paste"
+* install plugin "Auto-Copy to Clipboard" 
+
+Note: this will make auto-copy of selection, and paste to position of mouse cursor on middle-click. 
+But it will work only for "editor frame", and not work for: Console read-only editor, single-line inputs. So this method is limited.
