vi/vim editing — delete the character under the cursor In vi/vim normal mode, which command deletes the single character directly beneath (under) the cursor?

Introduction / Context:
Precise character-level edits are common when correcting typos. vi/vim provides single-keystroke deletion commands that work from normal mode without entering insert mode, enabling very fast text manipulation.

Given Data / Assumptions:

• We are in normal (command) mode.
• The goal is to remove exactly one character, the one under the cursor.
• No custom mappings are in place.

Concept / Approach:

The command x deletes the character under the cursor. Its uppercase counterpart, X, deletes the character to the left of the cursor (backspace-like). Other delete commands operate on larger text objects or ranges (for example, dd deletes the entire line, and D deletes from the cursor to the end of the line).

Step-by-Step Solution:

Verification / Alternative check:

Type a sample word, place the cursor on a letter, press x, and observe it vanish. Try X to see the difference (deletes to the left). Use u to undo if you delete the wrong character.

Why Other Options Are Wrong:

• X: deletes the character to the left, not under the cursor.
• dd: deletes the whole current line.
• D: deletes from the cursor to end of line.
• None of the above: incorrect because x is correct.

Common Pitfalls:

Being in insert mode and pressing x (which will just type the letter x); mixing up x and X; forgetting that counts speed up repeated deletions.

Final Answer:

x
