Thanks for telling me how to scroll with the stick. I could try that now too.
The display refresh rate depends on Windows theme (Classic (fastest), XP, Aero) as well as on the features enabled in UltraEdit like syntax highlighting, code folding, line change indicator, drawing of graphical lines, etc.
There are just 3 configuration settings regarding mouse, but no setting for controlling the scrolling in any way.
I prefer using the keys for scrolling because I need the keyboard to enter the text. So why should I move my ten fingers from the keyboard and and scroll with middle mouse button and the stick if using the keys is faster and can be better controlled. Available keys for scrolling respectively moving cursor (caret) amoung the standard keys PgUp, PgDn, Right, Left, Up, Down, Ctrl+Right, Ctrl+Left, Home, End, Ctrl+Home and Ctrl+End are:
- Ctrl+Up ... ScrollUpLine ... Scroll display up one line
- Ctrl+Down ... ScrollDownLine ... Scroll display down one line
- Alt+Add ... MoveLineToBottomofView ... Position active line at bottom of Window
- Alt+Clear or Alt+Multiply ... MoveLineToCenterofView ... Position active line at center of Window
- Alt+Subtract ... MoveLineToTopofView ... Position active line at top of Window
- Alt+PgDn ... CursorToBottomOfWindow ... Position cursor at bottom of Window
- Alt+PgUp ... CursorToTopOfWindow ... Position cursor at top of Window
- Alt+Left ... CursorToPreviousParagraph ... Position cursor at previous paragraph start
- Alt+Right ... CursorToNextParagraph ... Position cursor at next paragraph start
- Ctrl+Numeric pad 1 ... CursorToEndofPreviousWord ... Goto End of Previous Word
- Ctrl+Numeric pad 2 ... CursorToEndofNextWord ... Goto End of Next Word
The hotkeys for these commands can be customized in key mapping configuration dialog which should be done when often needed and numerical keypad is not available or hard to use as on Dell Latitude E6410.
Another method for scrolling by mouse/touchpad/stick is built-in in UltraEdit as in many other applications. Press shortly the middle button (or the wheel on a 2 button mouse with a wheel). The mouse cursor changes to a dot with 4 arrows. Now move the mouse/touchpad/stick and UltraEdit scrolls the display in the appropriate direction. To stop scrolling press again shortly the middle button. That scrolling mode works even if stick scrolling feature is disabled and is much easier to use because the middle button must not be hold all the time while moving the stick. Perhaps this method is better to use.
BTW: I looked now on all mouse settings available. There is a general Wheel
tab where it is possible to specify how many lines to move the display. The standard is 3 which is in my point of view too small. A number about 10 seems to be more practical.
And if clicking on general Hardware
tab after selecting pointing device Dell Touchpad
on button Properties
, the hardware options of the device opens. There is the tab Advanced Settings
and there the sample rate can be adjusted. It should not be too small and not too high. The default value is 100 which means every 10 ms the pointing device is polled for position information which is already higher than typical display refresh rate which is usually 60 Hz (16.66 ms). I changed now Wheel Detection
for Dell Touchpad
device to Detection Disabled
because there is definitely no wheel.
