VIM：Lexploreの新しいタブでファイルを開く方法

バラより:h netrw-t:

BROWSING WITH A NEW TAB                         netrw-t

Normally one enters a file or directory using the <cr>.  The "t" map
allows one to open a new window holding the new directory listing or file in
a new tab.

If you'd like to have the new listing in a background tab, use gT.

そして:h netrw-v：

BROWSING WITH A VERTICALLY SPLIT WINDOW                 netrw-v

Normally one enters a file or directory using the <cr>.  However, the "v" map
allows one to open a new window to hold the new directory listing or file.  A
vertical split is used.  (for horizontal splitting, see netrw-o)

Normally, the v key splits the window vertically with the new window and
cursor at the left.

t押すのではなく押すだけで、新しいEnterタブまたはv新しい垂直分割が開きます。
