Okular, KDE’s universal document viewer, has a really cool feature I’m using for years already: “Go > Forward” and “Go > Backward”. These two actions allow to quickly jump to positions in the document where you came from in a chronological order. Consider e.g. reading the phrase “As shown in , …”, and you want to know quickly lookup reference . So you click on it, and okular will jump to the list of references. And “Go > Back” will bring you back to exactly the position where you came from.
In fact, I removed the “Previous” and “Next”-page buttons from the toolbar in favor of the “Back” and “Forward” feature, which is much more useful to me :) Given that my colleagues were not aware of this feature (all experts in LaTeX and all using Kile and Okular), I thought to praise it here in a dedicated blog. Interestingly, the Okular Handbook is missing this feature. Any takers to fix this? :-) Update: This is also mentioned in the Okular handbook :-)
