滯後響應

Question

當我使用hjkl移動鍵（hnei對我來說，因爲我已經映射這些鍵與Colemak鍵盤佈局工作）在正常模式下，他們移動完全正常，沒有任何明顯的延遲。然而，在視覺模式下，與右移相對應的鍵（「我」）會導致非常令人討厭的滯後。我有一種感覺，我安裝的插件之一可能已經將命令映射爲「我」和另一個鍵的組合，但是我無法在任何地方找到它。爲什麼這種滯後發生？更具體地說，我是否在我的vimrc或插件中丟失了可能與我的移動映射衝突的內容？

Answer 1

:verbose vmap i 

會告訴你所有的視覺模式映射開始i（以及它得到了定義，這樣你就可以識別插件）。由於大多數「內部」文本對象以i開頭，並且在視覺模式下也可用，所以這種衝突確實是可能的。
