- EBCDIC code pages including 037 and 1140 with the euro
- Auto-reconnect and keep-alive for long-running sessions
Feature overview
AI explain this screen

Modern workspace
Tabbed sessions, split panes, a Ctrl+K command palette, crisp scalable fonts, dark mode, hotspots and a clear status line.
Copy as table
Select any screen region and paste it into Excel with the columns intact. Field-aware copy and paste everywhere else.
