vscode で矩形選択/コピー/ペースト / Rectangle selection, copy, paste with vscode

まず、デスクトップ環境のキーボード・ショートカットを(使っていない＆操作を奪われるので)削除

そして、vscode のキーボード・ショートカットを設定: cursorColumnSelect

矩形ペーストは、矩形コピーした直後のIカーソルが複数表示されている状態で貼り付けすればよい

Visual Studio Code でスクロールバー上の infor の色が明るすぎて他のマークが識別しづらいので色を変えてみる / In Visual Studio Code, the infor color on the scroll bar is too bright and other marks are difficult to identify, so try changing the color

vscode 1.37.1

本当にやりたかったのは Code Spell Checker 1.7.18 の結果をスクロールバーに表示したくなかったのです。水色のドットが沢山表示されて他が見えづらくなるのです。

settings.json を眺める限りでは、拡張機能自身に「スクロールバーに表示するinfor」／「非表示なinfor」等といった機能を実装するのは難しそうな感じです。

    "workbench.colorCustomizations": {
        // Scrollbar
        "editorOverviewRuler.infoForeground": "#002b52",    // "#75beff",
    },

"workbench.colorCustomizations": {

// Scrollbar

"editorOverviewRuler.infoForeground": "#002b52", // "#75beff",

その他の対応方法としては、やたらめったら単語登録するとか、infor の最大件数を10個とかにしてしまうとか？かな？
