Thanks for the report. I believe the observed slowdown was fixed in the latest ktexteditor.
this has really improved navigation, but there are still slowness issues when copying large selections. Example: when selecting 40 thousand lines and copying or cutting them to another tab
Nice. I guess there will be similar issue. IMHO there is no reason why copy should not be fast. The cutting case might be more difficult.
