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.
Below are several scenarios for using Next Edit Suggestion in JetBrains IDEs:
When you modify a parameter name in the surrounding context, NES automatically generates a suggestion to update the related parameter names.
NES supports existing functions by generating optimization and refactoring suggestions for existing code.
When you add a variable inside a code block, NES automatically generates a suggestion to replace how that variable is accessed in the subsequent code.
After adding an annotation to a field, NES automatically generates a suggestion to add the same annotation to the subsequent fields.
When you add a parameter to a function, NES generates suggestions to add the corresponding parameter at each subsequent call site of that function.

Enable Next Edit Suggestion
- JetBrains IDE
- Qoder CN 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. When you choose Inline or Auto, the Code Shifting option becomes available; it is not shown for Side by Side. Code Shifting controls whether existing code shifts to make room for the suggestion. Select the mode that fits your needs based on the descriptions below:
, or use the keyboard shortcut (⌘ ⇧ , on macOS or Ctrl shift , on Windows), select Personal Settings, and enable Next Edit Suggestion (NES).- Auto (default): Auto mode dynamically switches between Inline and Side by Side. When the combined pixel width of the changed code and the NES suggestion exceeds the visible editor area, it uses Inline; otherwise it uses Side by Side.

Inline: When NES is enabled and set to Inline, the display behavior depends on whether code shifting (moving code to make room between lines) is enabled. Specific behaviors:
Action Operation Effect Deletion only Single or multiple inline deletions (a word, characters within a word, or consecutive words all count as one). 
Delete a single line or multiple lines. 
Modification A single inline modification (word, characters within a word, or consecutive words all count as one), displayed as a word-level or phrase-level change. 
Modification within a single line, shown as an inline top-and-bottom diff view at character level. With code shifting (inserts a blank line)
Without code shifting (overlay effect)
Modifications across multiple consecutive lines, shown as an inline top-and-bottom diff view at character level. With code shifting (inserts a blank line)
Without code shifting (overlay effect)
Addition only Add a single line. With code shifting (inserts a blank line)
Without code shifting (overlay effect)
Add multiple consecutive lines. With code shifting (inserts a blank line)
Without code shifting (overlay effect)

Side by Side: When NES is enabled and set to Side by Side, the display behavior depends on whether code shifting is enabled. Specific behaviors:
Action Operation Effect Deletion only Single or multiple inline deletions (a word, characters within a word, or consecutive words all count as one). Delete a single line or multiple lines. Modification A single inline modification (word, characters within a word, or consecutive words all count as one), displayed as a word-level or phrase-level change. Single-line or multi-line changes. 
Addition only Add a single line or multiple lines (the suggestion appears at the line to be inserted, with the arrow aligned between the previous line number and the target line number). 
Use cases
- Interact with the current suggestion: After an inline suggestion is generated, hover over the Accept button to open the Qoder CN NES menu. In the menu, click Accept/Reject or press Tab/Esc on the keyboard to accept or reject the suggestion and close the menu. You can also click Settings to change the related configuration.
- Out-of-view within the same file: If the next predicted change is outside the current viewport, a button appears. Click the button or press Tab to jump to the target location.
- Out-of-view across files: If the next predicted change is outside the viewport and in a different file, a button appears. Click the button or press Tab to jump to the target location.
Rename
When you modify a parameter name in the surrounding context, NES automatically generates a suggestion to update the related parameter names.
Refactor
NES supports existing functions by generating optimization and refactoring suggestions for existing code.
Add variables, fields, parameters, or comments
Add a variable
When you add a variable inside a code block, NES automatically generates a suggestion to replace how that variable is accessed in the subsequent code.
Add a field
After adding an annotation to a field, NES automatically generates a suggestion to add the same annotation to the subsequent fields.
Add a parameter
When you add a parameter to a function, NES generates suggestions to add the corresponding parameter at each subsequent call site of that function.
