Text editor with synchronized scrolling and spell check features

I'm looking for a text editor that have these 2 features available: - Synchronized scrolling: You can have 2 tabs, side by side and you scroll both at the same time. - Spell check as you type (highlight, underline wo开发者_如何学运维rd, spell check on the fly) I have currently been using Notepad++ exactly because of this feature of Synchronized Scrolling, however the spell checking support is weak. I wouldn't mind even finding a word processor with these features, as my main use for synchronized scrolling is for translating texts, having both language texts on display.

I'll be glad for your suggestions.

For the Windows platform, the Zeus editor has the Synchronized Scrolling option (i.e. found on the Windows menu) but it does not have the dynamic spell checking feature.

The spell checking in Zeus is user initiated (i.e Spelling menu) and not dynamic.

NOTE: Zeus is shareware but there is also a freeware Zeus Lite version that has these the same two features.
