[0.7.1] GVIM - `:sh` Inserts Character Sequences on Control Character and Modifier Key Input

[jthodge]

Description

Providing common control character (e.g. <Delete>) and modifier key (e.g. ^-signals, ⌥-navigation commands) input into GVIM's :sh shell inserts character sequences instead of executing the input's respective expected behavior.

Affected Control Character(s):

• <Delete>

Affected Modifier Key(s):

• ^
• ⌥

N.B. There are likely other modifier key combinations that also insert characters, but I've not tested them exhaustively.

Steps to Reproduce

1. Open GVIM
2. Type :sh
3. Press <Enter>
4. Type <Delete>
5. Type a ^-signal (e.g. ^C, ^Z, ^\, ^T, etc.)
6. Type an ⌥-navigation command (e.g. ⌥+←, ⌥+→, etc.)

Expected Behavior

• <Delete> should delete the character(s) preceding the cursor.
• ^C should send a SIGINT, causing the current process to terminate.
• ⌥+← should move the cursor back one word, ⌥+→ should move the cursor forward one word.

Actual Behavior

<Delete>

• Single <Delete> press inserts ?b
• Two consecutive <Delete> presses inserts ?b followed by ?[J, to the left, producing ?[J?b
• Holding <Delete> for ~3 seconds inserts ?[J?[J?[J?[[J?b?[[J?b?[[J?b?[Jbb

^-signal

• ^C inserts ??C
• Other signals return their respective combination key prepended by ?? e.g. ??Z, etc.

⌥-navigation command

• ⌥+← inserts ?[Jkl
• ⌥+→ inserts ?[Jkr

Brief follow-up — individual arrow commands also insert character sequences:

• Pressing ↑ inserts ?ku
• Pressing ↓ inserts ?kd
• Pressing ← inserts ?kl
• Pressing → inserts ?kr
