+# VI mode
+
+Nel file `.bashrc` aggiungere:
+
+```bash
+set -o vi
+```
+
+Nel file `.inputrc`, invece, aggiungere:
+
+```bash
+#"\e[5~": history-search-backward
+#"\e[6~": history-search-forward
+
+set editing-mode vi
+# SHOW THE VIM MODE IN THE PROMPT (COMMAND OR INSERT)
+set show-mode-in-prompt on
+
+# SET THE MODE STRING AND CURSOR TO INDICATE THE VIM MODE
+#   FOR THE NUMBER AFTER `\e[`:
+#     0: blinking block
+#     1: blinking block (default)
+#     2: steady block
+#     3: blinking underline
+#     4: steady underline
+#     5: blinking bar (xterm)
+#     6: steady bar (xterm)
+
+set vi-ins-mode-string (ins)\1\e[5 q\2
+set vi-cmd-mode-string (cmd)\1\e[1 q\2
+
+$if mode=vi
+                set keymap vi-command
+                "k": history-substring-search-backward
+                "j": history-substring-search-forward
+#
+                set keymap vi-insert
+                "\C-l": clear-screen
+$endif
+```
+
+Quindi per visualizzare immediatamente gli effetti:
+
+```bash
+source .bashrc
+```
