Next Edit Suggestion (NES) dynamically predicts your next code change based on full code context, recent edits, and cursor position. Press Tab to apply the suggested change.
NES is available only in JetBrains IDEs and Qoder CN IDE. Upgrade Qoder CN to v2.5.4 or later in JetBrains, or follow the installation guide.
Enable Next Edit Suggestion
JetBrains IDE
-
Go to Settings > Qoder CN. Under NES Settings, select Enable NES (Next Edit Suggestion). This feature is disabled by default. When enabled, suggestion mode defaults to auto and code shifting defaults to No.
-
Three suggestion modes are available: inline, side by side, and auto. Code shifting applies only in inline and auto modes, and controls whether existing code shifts to accommodate suggestions.
Qoder CN IDE
In the upper-right corner of Qoder CN IDE, click the user icon
or use the keyboard shortcut (⌘ ⇧ , on macOS or Ctrl shift , on Windows), select Settings, and enable Next Edit Suggestion (NES).
Qoder CN IDE supports only auto mode, which automatically switches between inline and side-by-side display based on context.
-
auto (default): Dynamically switches between inline and side by side. Uses inline when the combined pixel width of the change and suggestion exceeds the visible editor area; otherwise uses side by side.
-
inline: Displays suggestions directly within your code. Whether existing code shifts or the suggestion appears as an overlay depends on the code shifting setting.
