Suggested Settings

For auto-complete, to assist in completion and set priority of completion, you may find these settings useful:

• Set in your preferences settings:
  
"editor.snippetSuggestions": "bottom",
"editor.suggest.localityBonus": true,
"editor.suggest.filterGraceful": true,
"editor.suggest.snippetsPreventQuickSuggestions": true,
"editor.autoIndent":"full",


Optional:   You can create a Task to launch TradeStation web help:

• Create a Task, such as:
  {
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [{
        // launch TradeStation web help, and search on reserved word
        "label": "EasyLanguage web help",
        "type": "shell",
        "presentation": {
           "echo": false,
           "reveal": "silent",
           "focus": false,
           "panel": "shared",
           "showReuseMessage": false
        },
        "command": "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe",
        "args": [
           "https://help.tradestation.com/10_00/eng/tsdevhelp/search.htm?q=${selectedText}"
        ],
        "problemMatcher": []
    }]
}


• Then create a keyboard shortcut (key binding in keybindings.json) and map a key (such as F1) to the Task to quickly launch help.   (double-click to select a keyword, then press the shortcut key.)   Here's an example keybinding:
  {
    "key": "f1",
    "command": "workbench.action.tasks.runTask",
    "args": "EasyLanguage web help",
    "when": "editorHasSelection"
}
