Do it using the recently introduced ui_brower scrolling mode, setting ui_browser.columns to the number of sort columns and then, when rendering each line, skipping as many initial columns as the user pressed the right arrow. As the user presses the left arrow, the ui_browser code will remove the scrolling counter and the left scrolling takes place. The right arrow key was an alias for ENTER, so people used to press it may get a bit annoyed at first, sorry! Ditto for ESC and the left key. Callchains can be left as is or we can, when rendering the Symbol column, store the at what position on the screen it is and then using ui_browser__gotorc() to print it from there, i.e. the callchain would move around with the symbol. Leaving it as is, i.e. at a fixed position, close to the left, saves precious screen real state for it, so I'm inclined to leave it as is now.
