[texworks] Page navigation using arrow keys

[Joan Solà]

Hello,

I have been using TexShop for ages, and this was my reason to use 
TexWorks when I needed a Tex editor for Linux. Then, I have been using 
TexWorks for about 4 years now.

Until today, I have been using version 4.5. Today I updated to 6.2.

I wonder where did this functionality go: in Texshop and earlier 
Texworks, I could position the page of the previewer at mid height in 
the window. Then, clicking left or right arrow keys, I could switch to 
the previous / next page, without losing the vertical position of my 
page. This way, I could zoom the page in, leaving top and bottom page 
margins out of the window, and still navigate across pages. The goal was 
to have all the text visible on the screen, but not the top and bottom 
margins, so that everything appeared significantly larger.

Honestly, this was one of the coolest features of texworks. When you 
have a small screen (i.e. when you are working on your laptop), it is a 
life saver, since displaying PDF pages showing top and/or bottom 
margins  means that the page needs to be too small to fit in the screen. 
In other words: showing the margins implies a poor use of the screen 
surface.

With the new version, I cannot do so. I can only do "next page" or 
"previous page" (even if attributed to the arrow keys), but when I do 
so, the appearing page is either at the top or the bottom of the window, 
meaning that either the full top margin is visible and I cannot see the 
lower text of my page, or the other way around.

Obviously, scrolling the page up/down after having switched pages is not 
the option I am looking for.

Is there any possibility to bring this feature back to life? It seems 
easy: on left/right arrow key, do:
- remember vertical position
- switch to previous/next page
- reposition vertically the result according to the remembered setting

Actually, and since we're already talking about this, this navigation 
feature could be improved even further, by also allowing the PDF window 
to skip left/right margins. Now, if the pdf page does not fit the window 
horizontally, then left/right arrows move the page horizontaly. My 
suggestion is that left/right arrows should only be used for page 
navigation, not for page repositioning, and that this navigation should 
remember horizontal and vertical position settings.

Thank you very much,

Joan
