From the website it looks like a Windows-oriented tool. If it weren't for your product I wouldn't have even guessed they had a Mac version. I bet they'd do much better with adoption if they customized their homepage screenshots to the platform viewing the page…
For others curious about Column Mode, here's their link with a nice video: https://www.ultraedit.com/support/tutorials-power-tips/ultra...
Apparently in VS Code you can do similar things: https://code.visualstudio.com/docs/editor/codebasics#_column...
1. Hold ⇧⌥ and drag for box select.
2. Press ⇧⌥⌘↓ for "column select down"
3. Run "Toggle column selection mode" and ⇧↓.
(Still looks like UltraEdit has some very powerful features for manipulating text in columns, like aligning whitespace).TIL. Looks great!
