Zoom with mouse wheel without CTRL

[PeterM32]

Hello,

is it possible to set sumatraPDF so that you can zoom with the mouse wheel without the additional key "CTRL".

That would be great. Thanks for your help.

Kind regards
Peter

How would you scroll?

[PeterM32]

Only with the mouse wheel (up = zoom in / down = zoom out)

Only with the mouse wheel (up = zoom in / down = zoom out)

??

In applications that handle documents (PDFs, .docx, .txt etc), the scroll wheel on the mouse is used to scroll up/down the document and CTRL+scroll_wheel is used to zoom.

What is the reason you want to change this convention in SumatraPDF?

If the mouse wheel was changed to zoom in/out, how would you scroll?

[PeterM32]

For that I use the hand tool ... just like in the Adobe Acrobat reader.

There is no possibility?

In some mices its possibe to "chord" thus holding both outer buttons may convert scroll to zoom.
This works with my mouse in SumatraPDF as well as other apps.

the scrolling is driven by OS hardware layer, to change mouse button/wheel behaviour is down to driver so one possibility is use a different driver hook at the hardware level and I always recommend HiRez X-Mouse as very versatile in handling per app situations

thank you...I'll try that once.

In my case Ctrl+Scroll does not zoom. Perhaps this is due to the fact that instead of the mouse wheel, I use a notebook trackpoint?

Constantly mashing Ctrl (Control) on my Lenovo laptop seemed to lock this in. I'm using a BT KeyBoard. Forgot KB was asleep, hit CTRL and it did nothing so by the time I was done venting on the CTRL key and the mouse wheel, I was stuck with zooming instead of scrolling with the mouse wheel. Nothing worked, except for hitting the CTRL key several times with less frustration.

Sounds like auto sticky keys ?? on my keyboard that does not seem to work with control, but I may have set it to ignore ? as pressing or holding same key does not trigger it currently, as per here aaaaaaaaaaaaaaaaaaaaaaaa h!

use right click and mouse wheel.
