Currently, Sublime Text supports the Ctrl+Minus and Ctrl+Shift+Minus for code navigation history.
Xcode has a neat way of handling this, albeit for entire files, by supporting two-finger swipe right and left. The manner and animation used are identical to the same gesture in Safari on macOS, if you’d like to give it a quick try.
Sublime Text could support this method of navigation, regardless of whether the animation is used / different files are actually navigated between. Currently, two-finger horizontal swiping seems unused in Sublime Text for macOS.
VSCode has supported this since sometime in 2017:
It would also be useful if this were customizable, for example some users may want this to switch between tabs. It might also be useful to use it as a “Find next” or “Find previous”.
Overall: It would be great to be able to use multi-touch gestures within Sublime Text, either for only a few specific items or bindable as general hotkeys.
