When using a line-oriented program like a shell on the main screen, they continue to scroll the terminal view by default. Editing and inserting in Files(Entering and Replacing Text): To edit the file, we need to be in the insert mode. Instead, it has a dynamic behavior where the keys automatically map to start/end-of-line when the alternate screen is active-e.g., when using a full-screen application like emacs, vim, screen or tmux. Note that in more-recent versions of macOS, Terminal no longer has explicit mappings for Home and End in the preferences by default. vi someFile While using vi, first move to the edit point, then enter into insert mode. This is what caused your unexpected char issue. Assuming these aren't in use by Vim, the simplest approach would be to customize Vim to accept these, using ~/.vimrc. In order for you to have discovered this problem, you pressed ' i ' to enter into insert mode and then used your arrow keys to navigate the correct line and edit point. Instead, they're mapped to the Emacs- and Bash-compatible sequences ESC [ 5 D and ESC [ 5 C. (On other OSes, Home and End are used for start/end of line, so Terminal provides them with the Shift modifier for symmetry.)Ĭontrol- Left Arrow and Control- Right Arrow are also mapped to "move to start/end of line" sequences by default, though they're different from the ones mapped to Shift- Home and Shift- End. So you may wish to change the keyboard map to send these other codes instead (Bash also understands them). Vim, Emacs, and some other programs send an escape sequence to put the terminal into “Application Cursor Mode”, where the Home/End keys send ESC O H and ESC O F, but Terminal (as of 10.9) does not implement this behavior. These sequences are understood by Bash, but you may have to customize Vim to understand them, or edit the mappings specifically for Vim. Similarly, Shift- Home and Shift- End are mapped to move to the start/end of the current line ( ESC [ H and ESC [ F). Also, many systems now set up command-mode arrow keys in vi by default, which also leads to. Also, see the View menu, which contains scrolling commands that use the Command modifier so they're available regardless of the terminal keyboard map. Y, scroll text down (cursor doesnt move unless it has to). However, you can use the following keyboard shortcuts too. You may have hit the CAPS LOCK key without noticing it.
#VI PAGE DOWN SHORTCUT KEY SERIES#
If you do this, I recommend you invert the meaning of the Shift modifier for these keys by swapping the mappings for the shifted and unshifted keys, so that the alternative behaviors are still available. In short press the Esc key and then press Shift + G to move cursor to end of file in vi or vim text editor under Linux and Unix-like systems. Joining Two Lines with J Sometimes while editing a file you end up with a series of short. Terminal > Preferences > Settings > Keyboard If you want these keys to send character sequences to the terminal without the Shift modifier, you can customize the keyboard map: You can also enter the insert mode by pressing a, A, o, as required.Terminal's default preferences map Shift- Page Up and Shift- Page Down to the character sequences that tell programs like Vim and Emacs to scroll ( ESC [ 5 ~ and ESC [ 6 ~). Make sure you press the right command otherwise you will end up making undesirable changes to the file. VI editor is case-sensitive so make sure you type the commands in the right letter-case. Note: You should be in the “ command mode” to execute these commands. ~ – Change case of individual character.S – Substitute entire line and begin to insert at the beginning of the line.s – Substitute one character under cursor continue to insert.R – Overwrite characters from cursor onward.C – Delete contents of a line after the cursor and insert new text.D – Delete contents of line after the cursor.o – Open a new line (goes into insert mode).U – Undo all changes to the entire line.A – Write at the end of line (goes into insert mode).a – Write after cursor (goes into insert mode).i – Insert at cursor (goes into insert mode).
