I have had this issue since I started using Tabnine for VS Code. I added inline suggestion mode in VS Code and it conflicts with the suggestion panel.
I want my VS Code to work as follows:
When typing stuff, hitting tab autocomplete Tabnine and hitting enter insert first pre-selected item in IntelliSense (suggestion panel).
My current situation:
Because the first item in the suggestion panel is not pre-selected, hitting enter will go to the next line, and hitting tab will auto-complete Tabnine inline suggestions.
Here is a screenshot of my editor when the first item is not pre-selected.
When hitting arrow down key, it will select the first item, and then hitting enter will insert the first item.
Some of my editor settings:
"editor.inlineSuggest.enabled": true,
"editor.suggestSelection": "first",
"editor.suggest.selectionMode": "never"
"[javascript]": {
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.suggestSelection": "recentlyUsed"
},
"[typescript]": {
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.suggestSelection": "recentlyUsed"
},

I'm guessing you set
"editor.suggest.selectionMode": "never"in order to "enable tab for tabnine"? But in doing so you made it so you have to manually use arrow keys to focus a suggestion.I'd instead suggest just unbinding tab from accepting a selected suggestion. Ex. like this in keybindings.json:
And then you can remove your
"editor.suggest.selectionMode": "never"to let it go back to the default value of"always".Actually, another thing you could try is to put
"editor.inlineSuggest.suppressSuggestions": truein your settings.json file. The setting's description:
